Best US Credit Cards for Grocery and Gas in 2026

Updated: October 2026.

For US households, groceries and gas are where the wrong card quietly costs hundreds of dollars a year, so pick by your spend, then order groceries at Walmart or Target through ShopBack before you pay, where ShopBack Cashback works like a discount, only easier than a promo code. A $95-fee card can beat a free one on the same shopping list, or lose to it. This guide shows you exactly where that line falls and how to build a setup around it.

The verdict

For a typical US household spending $500 to $700/month on groceries and $200 to $300/month on gas, the Amex Blue Cash Preferred ($95 annual fee, 6% at US supermarkets up to $6,000/year, 3% on US gas) (American Express) is the default winner, but only if your annual supermarket spend exceeds about $3,167 on grocery alone, or roughly $1,584 if you also earn about $47.50 a year more on streaming and transit. That figure is what we call the Family Grocery Floor: the point at which the Preferred's extra earning over the no-fee Blue Cash Everyday covers the $95 annual fee.

Below the floor, the Amex Blue Cash Everyday (no fee, 3% grocery, 3% gas, 3% online retail, each up to $6,000/year) (American Express) wins. For gas-heavy households with low grocery spend, the Citi Custom Cash (5% on top category up to $500 per billing cycle, no fee) (Citi) is stronger, though Citi stopped accepting new applications for it on May 28, 2026, so it is only available to existing cardholders. Costco-only fuel buyers should pair with the Costco Anywhere Visa (5% on Costco gas, 4% on other gas and EV charging, up to a combined $7,000/year) (Citi). A two-card setup that splits grocery and gas across separate issuers beats any single card once combined annual spend exceeds roughly $9,000.

The exceptions are Costco-loyal households (different math entirely), Sam's Club regulars (5% gas via Sam's Club Mastercard) (Synchrony), and anyone who shops primarily at Walmart, Target, or warehouse clubs (none of which code as supermarkets for grocery bonus categories).

Best US grocery and gas cards 2026: at a glance

Card	Annual Fee	Grocery Rate	Gas Rate	Cap	Best For
Amex Blue Cash Preferred	$95	6% US supermarkets	3% US gas	$6,000/yr grocery	High grocery households ($264+/mo)
Amex Blue Cash Everyday	$0	3% US supermarkets	3% US gas	$6,000/yr each	Low-to-mid grocery households
Citi Custom Cash	$0	5% top category	5% top category	$500/billing cycle top cat	Single-category households (closed to new applicants)
US Bank Cash+	$0	n/a (no grocery)	5% gas (if chosen)	$2,000/qtr	Gas-heavy, fee-averse
Chase Freedom Flex	$0	5% rotating quarters	5% rotating quarters	$1,500/qtr	Rotators willing to track
Costco Anywhere Visa	$0 (Costco mbsp required)	2% Costco	5% Costco gas / 4% other gas + EV	$7,000/yr gas + EV	Costco members
Sam's Club Mastercard	$0 (Sam's mbsp required)	1% Sam's Club (Club tier)	5% gas	$6,000/yr gas	Sam's Club members

The numbers show that no single card dominates both categories once you account for caps and category coding. The Amex Blue Cash Preferred earns the highest grocery rate (6%) and a competitive gas rate (3%), but its 6% cap of $6,000/year cuts off at $500/month in grocery spend. Anything above that earns just 1% (American Express). The Costco Anywhere Visa earns more on gas (5% at Costco gas, 4% on other gas) but only delivers 2% at Costco itself, which does not code as a supermarket on most other cards (Citi).

The Family Grocery Floor: where the $95 fee starts paying off

The single most important number in grocery card optimisation is the break-even point between the Amex Blue Cash Preferred (6% / $95 fee) and the Amex Blue Cash Everyday (3% / no fee). We call this the Family Grocery Floor.

The math is simple. The Preferred earns 3 percentage points more on grocery than the Everyday card. To recover the $95 annual fee, you need:

$95 ÷ 0.03 = $3,166.67 of grocery spend to recover the fee versus the Everyday card on grocery alone.

But the Preferred also earns 3% on gas (same as Everyday on gas), so gas spend does not move the breakeven. And the Preferred earns 6% on streaming (no extra room here over Everyday's online-retail bonus) and 3% on transit. Where the Preferred really separates is grocery alone.

A lower incremental floor applies if you also use the Preferred's streaming and transit bonuses: at $1,584/year of grocery spend, the extra 3% margin pays $47.50, and if streaming and transit add another $47.50, the total covers the ~$95 fee. Use $3,167/year ($264/month) if grocery is your only bonus spend, and $1,584/year ($132/month) only if you are confident of that streaming and transit earning.

The non-obvious claim: the Preferred is not "better" in any absolute sense; it is better only above the floor, and even above the floor it stops being meaningfully better once you cross the $6,000/year supermarket cap. Between $1,584 and $6,000 of grocery spend, every additional dollar earns 3 cents more than the no-fee alternative. Above $6,000, both cards drop to 1% on further supermarket spend, so the Preferred's lead stops growing.

Every card, broken down

Amex Blue Cash Preferred: the default grocery card above the floor

• Annual fee: $95 ($0 intro for the first year on current offers), subject to issuer terms
• 6% back at US supermarkets on the first $6,000/year (then 1%)
• 6% on select US streaming subscriptions
• 3% at US gas stations and on transit (rideshare, parking, tolls, trains, buses)
• 1% on everything else
• Welcome offer: typically $250 statement credit after $3,000 spend in first 6 months (current offer varies)

These rates and the $6,000 supermarket cap are confirmed on the issuer's own card page (American Express).

Worked example. A family spending $500/month on US supermarkets ($6,000/year) and $250/month on gas ($3,000/year) earns:

• Grocery: $6,000 × 6% = $360
• Gas: $3,000 × 3% = $90
• Total: $450 gross, $355 net of the $95 fee

The same family on Blue Cash Everyday (3% grocery, 3% gas) earns:

• Grocery: $6,000 × 3% = $180
• Gas: $3,000 × 3% = $90
• Total: $270, no fee

The Preferred wins by $85/year at this spend level, meaningful but not life-changing. Push grocery to $7,000/year and the gap stays at $85, because both cards drop to 1% on the $1,000 above their $6,000 supermarket caps.

Amex Blue Cash Everyday: the default below the floor

• Annual fee: $0
• 3% at US supermarkets on the first $6,000/year (then 1%)
• 3% at US gas stations on the first $6,000/year (then 1%)
• 3% on US online retail on the first $6,000/year (then 1%)
• 1% on everything else
• Welcome offer: typically $200 statement credit after $2,000 spend in first 6 months

Each 3% category carries its own separate $6,000/year cap, confirmed on the issuer's card page (American Express). For households spending less than $1,584/year on groceries (around $130/month or less, a single person or couple eating most meals out), this card is strictly better than the Preferred. The 3% online retail category is also a quiet workhorse: online clothing, household and other e-commerce orders add up to $3,000 to $5,000/year for many households, earning an extra $60 to $100 invisibly.

Citi Custom Cash: for the single-category household

• Annual fee: $0
• 5% on your top eligible category each billing cycle, up to $500 per billing cycle (then 1%)
• 1% on everything else
• Welcome offer: typically $200 Cashback after $1,500 spend in first 6 months
• Eligible categories include restaurants, gas stations, grocery stores, select travel, select transit, drugstores, home improvement stores, fitness clubs, live entertainment, and select streaming services

The 5% rate applies to the single eligible category you spend the most on in a billing cycle, capped at the first $500 of that category's spend, then 1% (Citi). Note that Citi stopped accepting new applications for the Citi Custom Cash Card on May 28, 2026; existing cardholders keep their accounts and rewards, but new applicants are steered to other Citi products. The card auto-selects whichever eligible category you spent the most on that month. For a household spending at least $500/month on gas and nothing close to that in any other category, this delivers up to $300/year in Cashback with zero fee and zero category tracking.

Worth it when: one category dominates your spend (typically gas, dining, or grocery) and you already hold the card. Avoid if: your spend is split evenly across multiple categories; the $500-per-cycle cap means anything above gets just 1%.

US Bank Cash+: choose your own categories

• Annual fee: $0
• 5% on two chosen categories on the first $2,000/quarter combined (then 1%)
• 2% on one chosen "everyday" category
• 1% on everything else
• Eligible 5% categories include gas stations + EV charging stations, restaurants, fast food, electronics, home utilities, cell phone, department stores, ground transport, movie theatres, gyms/fitness, sporting goods, select clothing, furniture

The 5%-on-two-chosen-categories structure and the $2,000-per-quarter combined cap are confirmed on the issuer's card page (U.S. Bank). The card does not include grocery as a 5% category. For gas-heavy households, choosing "gas stations + EV charging" delivers 5% on the first $2,000/quarter ($8,000/year cap). That beats every other gas card except Sam's Club Mastercard (with membership) and Citi Custom Cash (if gas is your top category and you already hold it).

Best for: fee-averse households where gas is one of two big variable categories. The category selection must be made each quarter; forgetting drops you to 1%.

Chase Freedom Flex: rotating quarters

• Annual fee: $0
• 5% on rotating quarterly categories on the first $1,500/quarter (then 1%)
• 5% on travel via Chase Travel portal
• 3% on dining and drugstores
• 1% on everything else
• Requires activation each quarter

The $1,500-per-quarter cap and mandatory quarterly activation are standard for the card. Historical Q1 to Q4 categories often include grocery stores, gas stations, Amazon, PayPal, and streaming, but the calendar shifts year to year. In 2026, Q2's 5% categories are Amazon, Whole Foods Market, and Chase Travel (plus donations to Feeding America), not gas stations (Chase). Activation is mandatory; missed activation means 1% for the entire quarter.

Worth it as a tertiary card alongside a primary grocery and a primary gas card. Avoid as a primary; the calendar is too unpredictable to plan annual spending around.

Route Costco and Sam's Club runs through ShopBack: Costco · Sam's Club · Walmart · Target

Costco Anywhere Visa: for Costco households only

• Annual fee: $0 (requires Costco membership, $65 to $130/year depending on tier)
• 5% on gas at Costco and 4% on other eligible gas and EV charging, on the first $7,000/year combined (then 1%)
• 3% on restaurants and eligible travel
• 2% at Costco and Costco.com
• 1% on everything else
• Cashback issued once annually as a Costco redemption certificate (not statement credit)

The 5%/4% gas split, the combined $7,000/year gas-and-EV cap, the 3%/2% tiers, and the annual February certificate payout are all confirmed on the issuer's rewards page (Citi). Costco gas is already 20 to 30 cents/gallon cheaper than nearby branded stations in most markets, and 5% back on that compounds the savings. A household filling up exclusively at Costco for $250/month earns $150/year in rewards in addition to the per-gallon discount, but only redeemable at Costco.

The non-obvious trap: the 2% at Costco itself is lower than the 3% you'd earn on grocery via Blue Cash Everyday, but Costco does not code as a supermarket on Amex, so Blue Cash Everyday earns just 1% there. The Costco Anywhere Visa is the only consumer card that meaningfully rewards Costco purchases.

Sam's Club Mastercard: for Sam's Club households only

• Annual fee: $0 (requires Sam's Club membership)
• 5% on gas at any gas station (not just Sam's Club), on the first $6,000/year of gas (then 1%)
• 3% on dining and takeout
• 3% on Sam's Club purchases for Plus members; 1% for Club members
• 1% on everything else
• Overall rewards capped at $5,000/year, issued as Sam's Cash redeemable at Sam's Club

The 5% gas rate, the $6,000/year gas-only cap, the 3% dining and takeout tier, and the tiered Sam's Club rate are confirmed on the issuer's program page (Synchrony). The 5% gas cap applies to gas alone; dining and takeout is a separate 3% category and does not share the $6,000 gas cap. The 5% gas rate is the highest non-Costco gas rate available on a no-fee card. For pure fuel buyers, this is the strongest gas card on the market in 2026.

Building your two-card setup

The strongest setup for most US households is two cards that each own a different category. Mixing issuers also spreads risk: if one issuer changes terms (Citi closed the Custom Cash to new applicants in 2026), the other half of your stack is unaffected.

Household Profile	Card 1 (Grocery)	Card 2 (Gas)	Combined Annual Fee	Earned at Typical Spend
High-grocery family ($600+/mo, $250/mo gas)	Amex Blue Cash Preferred	Citi Custom Cash (5% gas)	$95	~$427/yr net
Mid-spend household ($300/mo grocery, $200/mo gas)	Amex Blue Cash Everyday	US Bank Cash+ (5% gas)	$0	~$228/yr net
Low-grocery single ($120/mo grocery, $150/mo gas)	Amex Blue Cash Everyday	Citi Custom Cash (5% gas)	$0	~$133/yr net
Costco-loyal family ($500/mo grocery, $300/mo gas)	Costco Anywhere Visa	Amex Blue Cash Preferred (grocery overflow)	$95	~$500/yr net
Sam's Club regular ($400/mo grocery, $250/mo gas)	Amex Blue Cash Preferred	Sam's Club Mastercard	$95	~$343/yr net
Gas-heavy commuter ($150/mo grocery, $400/mo gas)	Amex Blue Cash Everyday	Citi Custom Cash (5% gas)	$0	~$295/yr net

Use this table when: your monthly grocery spend is stable (within ±$100). Adjust when: your spend varies seasonally (summer road trips, holiday hosting); in that case favour cards with annual rather than monthly caps (Amex Blue Cash family, Costco) over per-cycle-capped cards (Citi Custom Cash, US Bank Cash+). Note that Citi Custom Cash rows above assume you already hold the card, since it closed to new applicants in May 2026.

Go through ShopBack before you pay for online grocery orders: Target · Walmart · Sam's Club

Combining apps, coupons, cards and ShopBack

Credit card rewards are only one way to save. A single grocery purchase can earn rewards through several independent programs:

1. Credit card Cashback: the bank rewards the swipe
2. Grocery loyalty app (Kroger Plus, Safeway Just for U, Albertsons For U, Stop & Shop Go Rewards): the retailer rewards the loyalty event
3. Digital coupons clipped via the app: the manufacturer rewards the brand purchase
4. ShopBack (online grocery orders at ShopBack stores such as Walmart, Target and Instacart): go through ShopBack before you pay so part of the cost comes back
5. Receipt-scan apps (Ibotta, Fetch, Receipt Hog): third parties reward post-transaction data

A realistic combined in-store transaction at Kroger looks like: 6% on Amex Blue Cash Preferred + 2 to 4% in clipped digital Kroger Plus offers + 1 to 2% in Fetch points = roughly 9 to 12% effective discount on a $200 cart, or $18 to $24 saved per trip. For online orders at ShopBack stores, check the live Cashback rate on the store's ShopBack page before you pay.

For gas, the parallel stack is: 5% on Citi Custom Cash + 5 to 25 cents/gallon via GasBuddy Premium or Pay With GasBuddy + 5 to 25 cents/gallon via Upside (geo-targeted offers) = effectively 7 to 15% off depending on station and market.

In practice, this means the right card is the floor of your savings, not the ceiling.

Shop bulk groceries with Cashback: Sam's Club · Target · Chewy

When this does NOT apply

• You shop primarily at Walmart, Target, or warehouse clubs: None of these code as supermarkets on Amex, Chase, Citi, or US Bank. Blue Cash Preferred earns 1%, not 6%, at Walmart and Target. Use the Target Circle Card (formerly RedCard, 5% off at Target) for Target runs instead.
• You buy groceries through Instacart or DoorDash: These code as dining or delivery, not supermarkets; Amex Gold's 4x restaurants applies, Blue Cash Preferred does not.
• You buy gas at warehouse clubs (Costco, Sam's, BJ's) on a non-club card: Costco and Sam's gas pumps code as warehouse clubs, not gas stations, on most Amex and Chase cards. Blue Cash Preferred earns 1%, not 3%, at Costco gas. Use the Costco Anywhere Visa or Sam's Club Mastercard for in-club fuel.
• You spend less than $9,000/year combined on grocery and gas: Annual fees rarely break even at this spend level. Stick with a no-fee primary card; Blue Cash Everyday or Citi Custom Cash captures 70 to 80% of the upside without the fee drag.
• You drive an EV and rarely buy gas: Most "gas" categories don't include all EV chargers. US Bank Cash+ explicitly includes "gas stations + EV charging" as a 5% category. Citi Custom Cash includes some EV chargers but coverage is inconsistent. Tesla Supercharger billing often codes as utilities, not gas, on most cards.
• You're carrying a balance on the card: At a 22% APR, a single month of carrying $1,000 costs about $18 in interest, more than the $15 that a month of 3% back on $500 of grocery spend earns. Pay off in full first, then optimise rewards.

What's new in 2026

Two shifts in 2026 change the grocery-and-gas card math.

Citi closed Citi Custom Cash to new applicants on May 28, 2026 (Citi). Existing cardholders keep the 5% top-category structure. New applicants are steered to Citi Strata Premier or Citi Double Cash. For gas-heavy households without a warehouse-club membership, US Bank Cash+ (5% on chosen categories, first $2,000 per quarter combined, no fee) is now the strongest realistic pickup as a new gas card.

Chase Freedom Flex Q3 2026 5% categories include gas stations and EV charging, on the first $1,500 per quarter, activation required (Chase). This is the first Freedom Flex quarter in 2026 that includes gas, which shifts the tertiary-card layer for Chase-heavy households. Q2 covered Amazon, Whole Foods Market, and Chase Travel (Chase).

No changes to Amex Blue Cash Preferred, Blue Cash Everyday, Amex Gold, Costco Anywhere Visa, or BJ's One+ Mastercard rates and caps in 2026. Verify current welcome offers with each issuer before applying.

Frequently asked questions

What is the best US credit card for groceries in 2026?

For households spending more than about $3,167/year ($264/month) on US supermarkets (or about $1,584/year if you also use its streaming and transit bonuses), the Amex Blue Cash Preferred is the default winner: 6% back on the first $6,000/year (then 1%), plus 3% on gas, for a $95 annual fee. Below that grocery floor, the no-fee Blue Cash Everyday (3% grocery, 3% gas, and 3% online retail, each up to $6,000/year) wins because the $95 fee is not yet covered by the extra 3% margin.

What is the best US credit card for gas in 2026?

For gas-heavy households without a Costco membership, the Citi Custom Cash (5% on your top eligible category up to $500 per billing cycle, no annual fee) is the strongest single-category gas card, though Citi closed it to new applicants on May 28, 2026, so it is only an option for existing cardholders. Costco members should pair it with the Costco Anywhere Visa (5% on Costco gas and 4% on other gas and EV charging, up to a combined $7,000/year, then 1%). Sam's Club members get 5% on gas via the Sam's Club Mastercard, capped at $6,000/year on gas alone, then 1%.

Is the Amex Blue Cash Preferred worth the $95 annual fee?

Yes, if you spend more than about $3,167/year ($264/month) on US supermarkets. At that spend level the extra 3% over Blue Cash Everyday covers the $95 fee; regular streaming and transit spend on the Preferred can bring the floor down toward $1,584/year. Above that floor, every additional grocery dollar up to the $6,000 cap earns a net 3 cents more than the no-fee alternative. Below it, Blue Cash Everyday is the better pick.

Can I stack grocery store apps and credit cards together?

Yes. Grocery loyalty apps (Kroger Plus, Safeway Just for U, Albertsons For U), gas apps (GasBuddy, Upside), and credit card rewards all apply independently because they reward different parts of the transaction. A realistic combined rate at Kroger is roughly 6% card + 2 to 4% Kroger Plus digital coupons, for a total effective discount of 8 to 10%. For online grocery orders at ShopBack stores such as Walmart or Instacart, go through ShopBack before you pay so part of the cost comes back; check the live rate on the store's ShopBack page.

Do warehouse club credit cards count grocery purchases as supermarkets?

No. Amex, Chase, Citi, and US Bank all classify Costco, Sam's Club, BJ's, Walmart, and Target as warehouse clubs or superstores, not supermarkets. Grocery bonus categories do not apply at these merchants. This is the single largest source of confusion in grocery card optimisation.

Does Walmart count as a supermarket for grocery credit cards?

No. Walmart, Target, Costco, Sam's Club, BJ's, and most "superstore" merchants code as discount stores or warehouse clubs, not supermarkets, on every major US issuer (Amex, Chase, Citi, US Bank, Capital One). Grocery bonus categories do not apply. This is the single most common mistake in grocery card optimisation.

Is the Amex Gold's 4x grocery still better than Blue Cash Preferred's 6%?

No. At most realistic spend levels, Blue Cash Preferred (6% up to $6,000/year, $95 fee) outearns Amex Gold (4x up to $25,000/year, $325 fee) on grocery alone. Gold only pulls ahead when combined annual grocery + restaurant spend exceeds roughly $14,000, or when you redeem Membership Rewards via airline transfers at 1.5 to 2x cents per point.

Can I have both the Amex Blue Cash Preferred and Blue Cash Everyday?

Yes. Amex allows holding multiple Blue Cash variants simultaneously. Some households layer them: Preferred for grocery (6%), Everyday for online retail (3%). The combined $95 fee is justified if combined bonus-category spend exceeds about $6,000/year.

Do gas station snack and convenience purchases earn the gas bonus?

Yes. Most US issuers reward any transaction processed at a merchant coded as MCC 5541 (service stations) or 5542 (automated fuel dispensers), regardless of whether you bought fuel or a Slurpee. Wawa, Sheetz, QuikTrip, and similar chains that derive most revenue from food often code as gas stations, making them quietly excellent earners.

Are grocery store gift cards a way around the $6,000 cap?

No. Amex explicitly excludes gift cards and "cash equivalents" from grocery bonus categories. Most issuers will claw back rewards on flagged gift-card purchases. Don't try it.

Do warehouse club gas pumps earn the gas bonus on Amex or Chase?

No. Costco gas, Sam's Club gas, and BJ's gas all code as warehouse clubs, not gas stations, on Amex and Chase consumer cards. Only the warehouse club's own co-branded card (Costco Anywhere Visa for Costco; Sam's Club Mastercard for Sam's; BJ's One Mastercard for BJ's) earns the gas bonus at the club pump.

What's new with grocery and gas credit cards in 2026?

Two shifts matter this year. Citi closed Citi Custom Cash to new applicants on May 28, 2026, so the 5% top-category structure is only available to existing cardholders. Chase Freedom Flex's Q3 2026 5% categories include gas stations and EV charging (Chase). Amex Blue Cash Preferred, Everyday, Amex Gold, and Costco Anywhere Visa rates and caps are unchanged.

What is the best gas card for EV drivers in 2026?

US Bank Cash+ is the strongest single card because it explicitly includes gas stations plus EV charging as one of its 5% choose-your-own categories, capped at $2,000 per quarter combined (U.S. Bank). The Costco Anywhere Visa also covers EV charging at 4% (up to a combined $7,000 per year with gas). Tesla Supercharger billing often codes as utilities rather than gas or EV charging, so verify the merchant category code on your first billing cycle.

How do I earn Cashback on grocery orders through ShopBack?

Go through ShopBack before you pay and the Cashback tracks to your ShopBack account. Open Walmart (grocery pickup and delivery), Target, Sam's Club or Instacart from its ShopBack page and finish the order in the same visit. Check the live Cashback rate on each store's ShopBack page before you check out.

Which US retailers does ShopBack support for grocery and household shopping?

ShopBack US covers the main mass-market grocery and household routes: Walmart, Target, Costco, and Sam's Club. For pet groceries and household supplies, Chewy is a strong route for recurring orders. Traditional supermarkets (Kroger, Publix, H-E-B, Wegmans) typically run their own online channels; check the ShopBack all-stores page for the current list.

Where is the cheapest place to buy groceries online with Cashback?

No single retailer wins across every basket. For pantry staples and household essentials, Walmart tends to lead on unit price. For bulk buys, Costco and Sam's Club beat conventional supermarkets on per-unit cost even before Cashback. Compare the specific basket you buy most, then route through ShopBack on whichever retailer wins the sticker-price test.

Can I use ShopBack with credit card grocery bonuses?

Yes. Go through ShopBack before you pay and your card still earns its own rewards on the order. On an online grocery order at Walmart or Target, card rewards and ShopBack Cashback come separately. The current Cashback is shown on the store page on ShopBack before you buy.

How much Cashback can I earn on a typical monthly grocery run?

Cashback depends on which retailer you shop and their current published rate. A $500 monthly grocery spend split across Walmart, Target, and Costco can return a meaningful part of the cost through ShopBack, while your card still earns its bonus category. ShopBack does not guarantee a flat rate across grocery; check the live rate on each merchant page before you order.

When is the best deal window for stocking up on groceries and household essentials?

Black Friday and Cyber Monday drive the widest sitewide discounts at Walmart and Target. Warehouse-club coupon books at Costco and Sam's Club refresh roughly monthly and are strongest for household bulk buys.

Can I use ShopBack with a rotating grocery or gas category on my card?

Yes. A rotating 5% category on Chase Freedom Flex or Discover it comes from how you pay, while ShopBack Cashback comes from where you shop. Go through ShopBack to Sam's Club or Walmart before you pay for an online order and the card still earns its quarterly rate if the category matches. The current Cashback is shown on the store page on ShopBack before you buy, and you should confirm the quarterly category is active on your card before checkout.

How many days does grocery Cashback take to confirm in a ShopBack wallet?

Go through ShopBack before you pay for your grocery or delivery order and the Cashback is added to your ShopBack account. The current Cashback for each store, including Instacart and Walmart Grocery, is shown on its ShopBack page before you buy.

Can I earn ShopBack Cashback and credit card rewards on the same order?

Yes. ShopBack Cashback and credit card rewards are separate. Go through ShopBack before you pay, then use any accepted card at checkout, so part of the cost comes back through ShopBack while your card still earns its usual points, miles, or cash rewards.

Key takeaways

• If your household grocery spend exceeds about $3,167/year ($264/month), or $1,584/year with regular streaming and transit spend, the Amex Blue Cash Preferred ($95 fee) is the default grocery card: 6% up to $6,000/year covers a $500/month household
• If you spend less than the Family Grocery Floor on groceries, use the no-fee Blue Cash Everyday instead; the $95 fee is not yet earned back
• For pure gas optimisation, Citi Custom Cash (5% top category up to $500 per billing cycle) wins for non-Costco households that already hold the card (it closed to new applicants in May 2026); Costco Anywhere Visa (5% Costco gas / 4% other gas and EV up to a combined $7,000/year) wins for Costco members; Sam's Club Mastercard (5% gas up to $6,000/year) wins for Sam's members
• Walmart, Target, Costco, Sam's Club, and BJ's do NOT code as supermarkets on Amex, Chase, Citi, or US Bank; grocery bonus categories will not apply
• A two-card layered setup (one grocery card, one gas card, different issuers) outperforms any single card once combined annual grocery + gas spend exceeds $9,000
• Card rewards, grocery loyalty apps, clipped coupons and receipt-scan apps each pay out separately and together can push effective in-store grocery savings to roughly 9 to 12%; for online grocery orders, go through ShopBack before you pay
