Chase Freedom Flex vs Amex Blue Cash Preferred vs Citi Double Cash 2026: Which Cashback Card Fits Your Spending

Five percent on rotating categories, 6 percent on US supermarkets, 2 percent on everything. Chase Freedom Flex, Amex Blue Cash Preferred, and Citi Double Cash aim at three different spending profiles, and the wrong pairing costs the average US household about $340 per year in foregone cashback. This guide walks through each card's 2026 mechanics, maps them to typical US spending profiles, and shows how a category-first plus flat-back combination outperforms any single card for most households.

The verdict

For a US household in 2026, the right cashback card depends almost entirely on where the spend actually lands. Chase Freedom Flex is the best single-card choice for spending that can flex to match rotating quarterly bonus categories (Amazon, Target, warehouse clubs, PayPal, gas, streaming). Amex Blue Cash Preferred is the best single-card choice for households with consistent US supermarket spending above $200 a month, especially when combined with streaming and gas. Citi Double Cash is the best single-card choice for households that want to stop thinking about categories entirely and earn a predictable 2 percent flat.

For most US households, the mathematically strongest configuration is a category card paired with a flat card: use Chase Freedom Flex or Amex Blue Cash Preferred for bonus-category purchases, and use Citi Double Cash on everything else. That combination beats any single card at the same annual spend by $180 to $420 depending on the household profile.

What each card earns, in detail

Chase Freedom Flex earn structure in 2026

Chase Freedom Flex is a rotating-category cashback card issued by JPMorgan Chase. Ongoing earn structure as of 2026-07-28:

• 5 percent cash back on quarterly rotating categories, capped at $1,500 of spend per quarter ($6,000 per year at the bonus rate). Cardholders must activate the quarterly categories on the Chase website or app before earning at the bonus rate. Historical categories have included Amazon.com, Target, PayPal, wholesale clubs (Costco and Sam's Club), gas stations, streaming services, fitness clubs and gym memberships, and grocery stores. Chase publishes the rotating categories on the Freedom calendar page each quarter.
• 5 percent cash back on travel booked through Chase Travel portal.
• 3 percent cash back on dining, including takeout and eligible delivery services (DoorDash, Grubhub, Uber Eats, Instacart from restaurants).
• 3 percent cash back on drugstore purchases at Walgreens, CVS, Rite Aid, and other qualifying pharmacies. This does not include Walmart or Target pharmacy departments (which fall under retail store coding).
• 1 percent cash back on all other purchases with no cap.
• Cell phone protection up to $800 per claim, $1,000 per year, with $50 deductible, when the monthly cell phone bill is paid with Freedom Flex.
• No annual fee.
• No foreign transaction fee waiver: the card charges 3 percent on foreign transactions, so Freedom Flex is not ideal for international purchases.

Freedom Flex earns Ultimate Rewards points redeemable at 1 cent per point for cash back or statement credit. If you also hold a Chase Sapphire Preferred ($95 annual fee) or Sapphire Reserve, Ultimate Rewards points transfer at 1:1 to airline and hotel partners including United MileagePlus, Southwest Rapid Rewards, Air Canada Aeroplan, British Airways Executive Club, Hyatt World of Hyatt, IHG One Rewards, and Marriott Bonvoy. That transferability materially increases the effective value of Freedom Flex rewards for households already inside the Chase ecosystem.

Amex Blue Cash Preferred earn structure in 2026

American Express Blue Cash Preferred is a supermarket-and-transit cashback card. Ongoing earn structure as of 2026-07-28:

• 6 percent cash back at US supermarkets, capped at $6,000 of spend per calendar year (roughly $500 per month). Above the cap, US supermarket spend earns 1 percent. US supermarkets exclude Walmart, Target, warehouse clubs (Costco, Sam's Club, BJ's), and specialty food stores. Whole Foods and Trader Joe's do code as US supermarkets on Amex.
• 6 percent cash back on select US streaming subscriptions, uncapped. Eligible services have included Netflix, Hulu, Disney Plus, HBO Max, Peacock, Paramount Plus, Apple TV Plus, YouTube TV, and several music streaming platforms. Amex publishes the eligible-service list on the card page and updates it periodically.
• 3 percent cash back on transit, including taxis, rideshare (Uber, Lyft), parking, tolls, trains, and buses. Airline tickets do not qualify as transit under Blue Cash Preferred coding.
• 3 percent cash back on US gas stations, uncapped.
• 1 percent cash back on all other purchases with no cap.
• $84 Disney Bundle credit ($7 monthly credit toward the Disney Bundle after enrollment; this is an ongoing benefit as of 2026-07-28 but subject to change).
• Return protection, purchase protection, and extended warranty benefits standard on Amex mid-tier cards.
• $95 annual fee after a $0 introductory annual fee for the first year (verify current promotional offer before applying).
• No foreign transaction fee waiver: 2.7 percent foreign transaction fee applies.

Blue Cash Preferred earns Reward Dollars, redeemable as statement credit at $25 increments. Reward Dollars do not transfer to Membership Rewards, cannot be used for travel-partner transfers, and cannot be pooled with a different Amex card's rewards. This is Blue Cash Preferred's biggest structural limitation: the redemption ceiling is 1 cent per Reward Dollar (equivalent to cash back), full stop.

Citi Double Cash earn structure in 2026

Citi Double Cash is a flat-rate cashback card that pays in two halves. Ongoing earn structure as of 2026-07-28:

• 1 percent cash back when you make a purchase.
• 1 percent additional cash back when you pay off that purchase.
• Effective 2 percent flat cash back on all purchases with no category caps and no rotating categories to activate.
• No annual fee.
• No foreign transaction fee waiver: 3 percent foreign transaction fee applies.
• Balance transfer promotion available at the introductory 0 percent APR for the first 18 months (subject to change; balance transfer fees apply). This benefit is worth noting for households carrying a balance elsewhere but is not a cashback earning feature.

Citi Double Cash earns ThankYou points at 2 points per dollar (1 when you buy, 1 when you pay), redeemable at 1 cent per point for cash back or statement credit. If you also hold a Citi Strata Premier ($95 annual fee) or higher tier ThankYou card, ThankYou points transfer at 1:1 to airline partners including Air France KLM Flying Blue, Emirates Skywards, Etihad Guest, JetBlue TrueBlue, Qatar Airways Privilege Club, Singapore Airlines KrisFlyer, Turkish Airlines Miles and Smiles, Virgin Atlantic Flying Club, and Wyndham Rewards, plus Choice Privileges. The Citi transfer partner list is different from Chase's and is meaningfully strong for international premium cabin redemptions.

The 2 percent flat rate is Double Cash's core value proposition: no thinking, no activation, no category rotation, no supermarket exclusions. Every purchase earns the same rate.

Cashback earned by household spending profile

The following table maps each card's earn rate to a typical US household spending profile drawn from Bureau of Labor Statistics Consumer Expenditure Survey categories, annualized to net cashback earned per year at a mid-income household spending level.

Annual spend by category	Freedom Flex	Blue Cash Preferred	Double Cash
$6,000 US supermarkets	$60	$360	$120
$3,000 US gas	$30	$90	$60
$800 streaming	$8	$48	$16
$3,000 dining	$90	$30	$60
$600 drugstores	$18	$6	$12
$2,000 transit and rideshare	$20	$60	$40
$4,000 rotating category eligible spend (Amazon, Costco, Target, PayPal)	$200 (assumes fully within $6,000 annual bonus cap)	$40	$80
$8,000 everything else	$80	$80	$160
Total gross cashback	$506	$714	$548
Annual fee	$0	$95	$0
Net cashback	$506	$619	$548

This illustrative profile shows Blue Cash Preferred winning as a single card for a household with substantial supermarket, streaming, and gas spend even after the $95 fee. Citi Double Cash beats Freedom Flex on this profile because the rotating-category bonus does not fully offset the 1 percent penalty on everything else. The 4-category and 5-category bonuses on Blue Cash Preferred aggregate more meaningfully than any single quarterly rotating category on Freedom Flex.

However, a two-card configuration (Blue Cash Preferred for its bonus categories plus Citi Double Cash for everything else) captures $714 on Blue Cash Preferred bonus spend plus $160 on the $8,000 non-bonus everything-else category at 2 percent flat, for total gross cashback of $874, net of $95 fee, or $779 net cashback. That is $160 more than Blue Cash Preferred alone and $273 more than Double Cash alone on the same spend.

The two-card strategy dominates the single-card strategy for most US households above roughly $15,000 in annual credit-card spend.

How to decide, by spending profile

Profile A: Grocery-heavy family, $500 to $700 a month at US supermarkets

Amex Blue Cash Preferred is the correct primary card. At $500 a month, Blue Cash Preferred earns $30 a month at 6 percent versus $10 on Citi Double Cash or $5 on Freedom Flex (1 percent baseline). Over a year, that gap is $240 to $300, which more than covers the $95 fee. Pair Blue Cash Preferred with Citi Double Cash for everything outside the six bonus categories (supermarkets, streaming, gas, transit; the streaming and transit bonuses are stackable). Freedom Flex is unnecessary unless you plan to activate quarterly rotating categories consistently.

Profile B: Costco and warehouse-club household

Freedom Flex is worth having only in quarters when warehouse clubs are the rotating category (roughly one quarter every 12 to 18 months historically). For year-round Costco spend, Citi Double Cash at 2 percent flat is the ongoing baseline. Amex Blue Cash Preferred does not code Costco or warehouse clubs as supermarkets, so Blue Cash Preferred earns only 1 percent at Costco. Costco itself accepts Visa and its own Costco Anywhere Visa (Citi-issued) earns 2 percent at Costco warehouse, so warehouse-club shoppers often carry a Costco cobrand card as their warehouse-specific tool alongside Double Cash for elsewhere.

Profile C: Dining and rideshare-heavy urban household

Freedom Flex is the correct primary card for pure dining and drugstore capture at 3 percent, but Blue Cash Preferred wins on transit and rideshare at 3 percent. If dining spend exceeds transit spend by a meaningful margin, Freedom Flex plus Double Cash covers most bases. If transit and rideshare dominate the household budget (common in New York City, San Francisco, Chicago, Boston, DC), Blue Cash Preferred plus Double Cash captures more value even after the $95 fee. Chase Sapphire Preferred ($95 fee) or Sapphire Reserve is often a stronger dining card for households already in the Chase ecosystem, because Sapphire earns 3x Ultimate Rewards points on dining with meaningful travel-transfer partner value.

Profile D: Streaming and subscription-heavy household

Amex Blue Cash Preferred is decisively the best card for streaming, at 6 percent on Netflix, Hulu, Disney Plus, HBO Max, YouTube TV, and other eligible services. A household spending $80 a month across five streaming platforms earns $57.60 a year in Blue Cash Preferred cashback on streaming alone, versus $9.60 on Freedom Flex or $19.20 on Double Cash. Multiply across the full Blue Cash Preferred bonus category set and the fee is easily justified.

Profile E: Set-and-forget minimalist household

Citi Double Cash is the correct choice. No quarterly category activation, no supermarket exclusion list to memorize, no annual fee to break even on. At 2 percent flat on everything, Double Cash beats Freedom Flex on non-bonus spend and beats Blue Cash Preferred once the fee is factored in on any household spending less than $2,375 a year at US supermarkets. For a household that dislikes managing cards, Double Cash alone captures more value than most single-card cashback options in the US market.

Profile F: Travel-adjacent household inside Chase ecosystem

Freedom Flex plus Chase Sapphire Preferred ($95 fee) plus Chase Freedom Unlimited (no fee, 1.5 percent on everything) is the classic Chase Trifecta configuration. Freedom Flex captures rotating 5 percent, dining 3 percent, drugstore 3 percent. Sapphire Preferred captures dining and travel at 3x Ultimate Rewards. Freedom Unlimited captures everything else at 1.5x Ultimate Rewards (better than Freedom Flex 1 percent floor). All three cards feed into the same Ultimate Rewards account, and Sapphire Preferred unlocks 1:1 transfer to airline and hotel partners including Hyatt, United, and Southwest. This trifecta is the highest-ceiling US cashback configuration for households that redeem points for travel.

Profile G: Balance-carrying household paying interest

None of the three cards is the correct choice while carrying a balance. Cashback rewards are net-negative when APR interest exceeds cashback earn rates (which it always does at prevailing US credit card APRs of 18 to 29 percent). Pay down the balance before optimizing category cashback. Citi Double Cash's 18-month 0 percent APR balance transfer promotion (as of 2026-07-28, subject to change) is a legitimate tool for consolidating and paying down existing high-APR debt.

Personas, in practice

Persona A: The Suburban Grocery Household

Two adults and two kids, spending roughly $9,000 a year at HEB, Kroger, Publix, or Safeway. Amex Blue Cash Preferred captures the first $6,000 at 6 percent ($360) and the remaining $3,000 at 1 percent ($30). Total supermarket cashback: $390. Add $50 a month in streaming subscriptions (Netflix, Disney Plus, YouTube TV) at 6 percent, another $36 a year. The card clears the $95 fee three times over on supermarkets alone.

Persona B: The Urban Single Professional

One adult in Manhattan, spending $400 a month on dining out and delivery, $200 a month on Uber and subway, $50 a month on streaming. Blue Cash Preferred captures streaming at 6 percent ($36) and transit at 3 percent ($72), but dining earns only 1 percent ($48). Freedom Flex captures dining at 3 percent ($144) but streaming at 1 percent ($6). Total on dining plus transit plus streaming: Blue Cash Preferred earns $156, Freedom Flex earns $174, Double Cash earns $130. Freedom Flex is the marginally better single card here, though the gap is small enough that any of the three works.

Persona C: The Costco Shopper

Household spending $6,000 a year at Costco, $2,000 a year at Amazon, $3,000 a year at gas stations that happen to be Shell or Chevron, $8,000 elsewhere. Costco Anywhere Visa (Citi-issued) is the correct warehouse card at 2 percent Costco spend plus 4 percent Costco gas. Freedom Flex can capture Amazon at 5 percent during quarters where Amazon rotates in (typically Q4 each year), and gas stations at 5 percent during other quarters. Double Cash covers everything else. The right configuration is three cards: Costco Anywhere Visa for Costco, Freedom Flex for rotating quarterly categories, Double Cash for the everything-else floor.

Persona D: The Cross-Country Traveler

Household spending $8,000 a year on travel, $4,000 on dining, $2,000 on supermarkets. Blue Cash Preferred earns modestly here because travel airline tickets do not code as transit under BCP. Freedom Flex captures 5 percent on Chase Travel bookings. Sapphire Preferred (if paired with Freedom Flex) earns 3x Ultimate Rewards on dining and 2x on travel, redeemable for meaningfully more than 1 cent per point at partners like Hyatt. This household should not be optimizing pure cashback; they should be inside the Chase ecosystem or Amex Membership Rewards ecosystem for travel-partner redemptions.

Persona E: The Set-and-Forget Minimalist

One card, one number, no rotating category to memorize. Citi Double Cash at 2 percent on everything, no annual fee, no supermarket exclusion list, no rotating activation. Predictable, boring, effective. A household spending $30,000 a year on a Double Cash card earns $600 in cashback per year with zero mental overhead.

---

What each card is not for

Chase Freedom Flex is not for international purchases (3 percent foreign transaction fee) and not for households that will forget to activate the quarterly rotating category. Roughly a third of Freedom Flex cardholders fail to activate at least one quarter per year, foregoing an estimated $50 to $200 of category cashback per unactivated quarter.

Amex Blue Cash Preferred is not for households whose supermarket spend runs primarily through Walmart, Target, or warehouse clubs (none of which code as US supermarkets on Amex). It is also not for households that would prefer to redeem points for premium travel; Blue Cash Preferred earns cash-only Reward Dollars.

Citi Double Cash is not for households with high concentration in a specific category (grocery, gas, dining) where a specialized card at 3 to 6 percent easily beats the 2 percent flat rate. It is also not for households that want a welcome bonus; Double Cash's sign-up bonus has been inconsistent and often absent.

None of the three is a strong international travel card. All three charge foreign transaction fees, none offers airline lounge access, and Blue Cash Preferred does not carry travel-focused perks like Global Entry credit or travel insurance on the level of Sapphire Preserve or Amex Platinum.

Where ShopBack fits into the stack

ShopBack cashback lands separately from credit card rewards. When you click through ShopBack to a merchant site (sephora.com, ulta.com, samsung.com, priceline.com, and 2,000+ other US partners), cashback accumulates on the ShopBack account rather than on the card. The credit card still earns its normal points or cashback on the same purchase.

For a Blue Cash Preferred user shopping through the ShopBack ulta-beauty merchant page, the transaction earns 1 percent Amex Reward Dollars (Ulta is not a US supermarket) plus the current published ShopBack rate on Ulta. For a Freedom Flex user shopping through the ShopBack samsung merchant page during a Freedom Flex Amazon-Target-quarter, the transaction earns whatever the current quarterly bonus is on Chase (if applicable) plus the ShopBack Samsung cashback rate. ShopBack is a rate-additive layer, not a substitute for card cashback.

The highest-value stack in 2026 for online shopping at ShopBack-partner retailers is: credit card bonus category rate plus ShopBack cashback rate plus any retailer loyalty program benefit (Sephora Rouge, Ulta Diamond, Best Buy My Best Buy Plus, Samsung Rewards). Layering all three is standard practice for cashback-aware US households.

Scope and exclusions

This guide covers three flagship US-market consumer cashback cards as of 2026-07-28. Card terms, earn rates, annual fees, sign-up bonuses, and category eligibility change frequently; verify current terms directly with each issuer before applying.

This guide does not cover:

• Business credit cards (Chase Ink Cash, Amex Business Blue Cash, Capital One Spark Cash), which have different earn structures targeting business expense categories.
• Premium travel cards (Chase Sapphire Reserve, Amex Platinum, Capital One Venture X), which optimize for travel and lounge benefits rather than pure cashback.
• Store cobrand cards (Amazon Prime Visa, Target RedCard, Best Buy Visa, Costco Anywhere Visa), which typically outearn generalist cards inside their specific retailer.
• Cards for consumers with limited credit history (secured cards, subprime cards, credit-builder cards), which follow different approval and reward structures.
• International or expatriate credit card use with foreign transaction fee optimization.
• Balance transfer strategy in detail (Citi Double Cash offers a promotional 0 percent APR window, but balance transfer strategy warrants a separate treatment).

Anyone applying for a credit card should review the current issuer terms, disclosure, and fee schedule directly. This article is editorial content and does not constitute financial advice.

What this means for card selection

Do not pick the card with the highest headline rate on a single category if that category is not a meaningful portion of your household spend. A 6 percent supermarket rate is meaningless for a household that eats out five nights a week and grocery-shops at Costco. A 5 percent rotating category is meaningless for a household that will not activate the quarterly rotation.

Do pick a category card that matches your top two or three spending categories, plus a flat card that catches everything else. The two-card configuration outperforms any single-card configuration for most households above $15,000 in annual credit-card spend.

Do factor the annual fee into total cashback math. Blue Cash Preferred's $95 fee is not a dealbreaker if bonus-category spend clears the break-even threshold, but it is a dealbreaker for a household with modest supermarket, streaming, and transit spend.

Do stack ShopBack cashback for online purchases at partner merchants. The rate is additive on top of card cashback, not competitive with it. This adds a third layer of value on categories where credit card cashback alone caps out at 1 to 2 percent.

Do not chase sign-up bonuses without a long-term hold plan. A $250 welcome bonus on Blue Cash Preferred is worth less than $50 a year in incremental supermarket cashback over five years of holding the card. The long-term earn rate matters more than the one-time bonus for anyone planning to hold the card for the foreseeable future.

Frequently asked questions

Earn rate per card on rotating, groceries, everyday, and travel?

Chase Freedom Flex earns 5 percent on rotating quarterly categories capped at $1,500 per quarter, 5 percent on Chase Travel bookings, 3 percent on dining and drugstores, and 1 percent on everything else including groceries, gas, and streaming. Amex Blue Cash Preferred earns 6 percent on US supermarkets up to $6,000 per year, 6 percent on select US streaming, 3 percent on transit and US gas, and 1 percent on everything else. Citi Double Cash earns 2 percent flat on all purchases (1 percent when you buy plus 1 percent when you pay). No card earns bonus on both groceries and rotating categories, which is why the two-card configuration outperforms a single card for most households.

Annual fee versus cashback earned?

Chase Freedom Flex has no annual fee. Citi Double Cash has no annual fee. Amex Blue Cash Preferred charges $95 annually after a $0 introductory year. Blue Cash Preferred breaks even against Double Cash at roughly $2,375 in annual US supermarket spend; below that threshold, Double Cash beats Blue Cash Preferred. Above that threshold, Blue Cash Preferred wins. Any household spending more than $200 a month at US supermarkets clears the fee, and adding streaming and gas category bonuses lowers the break-even threshold further.

Sign-up bonus current?

Sign-up bonus offers change frequently and are not published guarantees. As of 2026-07-28, verify the current welcome offer on each issuer's landing page. Historical baselines are useful for planning: Chase Freedom Flex has typically offered $200 cash back after $500 spend in the first three months, Amex Blue Cash Preferred has typically offered $250 statement credit after $3,000 spend in six months, and Citi Double Cash has run inconsistent welcome bonuses ranging from $200 to none. Do not choose a card based on welcome bonus alone; ongoing earn rate is more consequential over multi-year hold periods.

Redemption flexibility?

Chase Ultimate Rewards points (earned by Freedom Flex) redeem at 1 cent per point for cash back, statement credit, or Chase Travel bookings; with a Chase Sapphire Preferred or Reserve in the same account, points transfer 1:1 to airline and hotel partners including Hyatt, United, Southwest, British Airways, Air Canada, and Marriott. Amex Blue Cash Preferred Reward Dollars redeem only as statement credit at $25 minimums and do not transfer to Membership Rewards. Citi ThankYou points (earned by Double Cash) redeem at 1 cent per point for cash back; with a Citi Strata Premier or higher, ThankYou points transfer 1:1 to airline partners including Air France KLM, Emirates, Singapore Airlines, Virgin Atlantic, and JetBlue. Chase and Citi both offer flexible ceiling; Amex Blue Cash Preferred is cash-only.

Best card for what household spend?

For a US household with grocery spend above $200 a month plus meaningful streaming and gas, Amex Blue Cash Preferred is typically the best single-card choice despite the $95 fee. For a household that reliably activates quarterly rotating categories and can shift purchases to Amazon, Target, Costco, PayPal, gas, or streaming during the right quarter, Chase Freedom Flex captures 5 percent on up to $6,000 of category spend. For a household that wants no category management, no rotation, no supermarket exclusion list, Citi Double Cash at 2 percent flat is the simplest choice. For most US households above $15,000 in annual card spend, the strongest configuration is one category card (Freedom Flex or Blue Cash Preferred, chosen based on spending pattern) plus Citi Double Cash as the everything-else card.

Do these three cards stack with ShopBack cashback?

Yes. ShopBack cashback is earned separately from credit card rewards. Click through ShopBack to a partner merchant, complete the purchase with your card, and cashback lands on both accounts. The credit card earns its normal points or cashback rate; ShopBack earns the current published merchant rate on top. This is the highest-value US cashback stack for online purchases at ShopBack merchants including Sephora, Ulta Beauty, Best Buy, Priceline, Samsung, and many others.

What is the foreign transaction fee on each card?

Chase Freedom Flex charges 3 percent foreign transaction fee. Amex Blue Cash Preferred charges 2.7 percent foreign transaction fee. Citi Double Cash charges 3 percent foreign transaction fee. None of the three is a good international travel card; for international purchases, prefer a card with no foreign transaction fee such as Chase Sapphire Preferred, Capital One Venture X, Wells Fargo Autograph, or Bank of America Travel Rewards.

Is Chase Freedom Flex the same as Chase Freedom Unlimited?

No. Freedom Flex earns rotating 5 percent categories quarterly. Freedom Unlimited earns 1.5 percent flat on everything with 3 percent on dining and drugstores. Chase issues both under the Freedom brand but they are structurally different products. Many households in the Chase ecosystem hold both cards alongside a Sapphire Preferred or Reserve; the three-card Chase Trifecta is a well-known configuration.

Does Blue Cash Preferred code Whole Foods and Trader Joe's as supermarkets?

Yes, both code as US supermarkets on Amex Blue Cash Preferred. Costco, Sam's Club, BJ's, Walmart, Target, and specialty food stores (butcher shops, wine shops, farmers' markets) do not code as US supermarkets. Standalone supermarkets and grocery chains (Kroger, Publix, Safeway, HEB, Wegmans, ShopRite, Giant, Stop and Shop, Ralphs, Food Lion, Meijer, Sprouts) all code correctly.

Is Double Cash's 18-month 0 percent APR balance transfer offer available in 2026?

Verify current terms directly on Citi's Double Cash page. Balance transfer promotional APR windows change frequently, and the specific terms (balance transfer fee percentage, promotional duration, minimum credit line) are card-application-specific. As of 2026-07-28, the balance transfer promotional APR has been available on Double Cash consistently for several years, but the specific promotional length and transfer fee have adjusted periodically.
