Costco

Costco's own promotions typically apply automatically as Sale Book event pricing, Warehouse Hot Buys and Online-Only markdowns rather than as always-on promo codes at checkout, since Costco's Everyday Low Price positioning does not typically issue site-wide voucher codes. Occasional member-only offers on select Costco Travel packages and Costco.com categories surface at checkout without a code. Third-party voucher codes pasted at Costco checkout, or any voucher or promo code not featured on ShopBack, will block cashback per the exclusion list. Sticking to Costco's own automatic Sale Book pricing and member-only offers is the safer route. Currently ShopBack US cashback on Costco applies to new membership sign-ups only, not to regular Costco purchases, per the rate panel above.

The Costco Sale Book is Costco's monthly member savings booklet covering roughly two to four weeks of instant-savings pricing on hundreds of Kirkland Signature and national-brand SKUs across grocery, electronics, appliances, home, auto and health. The Sale Book is mailed to Executive Members and posted on Costco.com, and pricing applies automatically at the register or online checkout with no promo code required. Sale Book windows typically stagger across the month with new SKUs added weekly. Deepest cuts usually land on Kirkland Signature pantry, cleaning and paper, small kitchen appliances, seasonal apparel and TVs. New Costco memberships started from the ShopBack Costco page earn cashback at the current published tier above.

Kirkland Signature is Costco's private-label brand spanning pantry, dairy, frozen, snacks, coffee, wine and spirits, cleaning, paper, over-the-counter medicine, vitamins, apparel basics, batteries and cookware. Kirkland Signature is positioned in the warehouse club as a lower-price alternative to the national-brand SKU on the same shelf, typically 20 to 30 percent below the equivalent national brand, and many Kirkland Signature items are co-packed by the same manufacturer as the national-brand SKU. Consumer reviews rate the Kirkland Signature range as generally comparable to or better than national brands on core pantry, cleaning and vitamins staples. Bulk buying at Costco warehouse pricing plus Kirkland Signature substitution is the primary saving strategy for households at scale.

Costco Black Friday 2026 lands on the last Friday of November, with Costco typically running a Black Friday event that stretches the full Black Friday weekend into Cyber Monday. Costco's Black Friday event is applied automatically as Sale Book and Online-Only pricing without a promo code, and is available to all Costco members regardless of tier. Deepest cuts usually land on TVs, laptops, tablets, small kitchen appliances, mattresses, jewellery, tyres and Kirkland Signature seasonal food. A Cyber Monday Online-Only extension typically follows. Post-Holiday clearance runs the week after Christmas through mid-January on remaining seasonal stock. A new Costco membership sign-up started from the ShopBack Costco page earns cashback at the current published tier.

For US households optimising for lowest cash outlay on a large-basket grocery run (pantry staples, cleaning and paper, meat, dairy, frozen, coffee, snacks), Costco is typically most competitive on per-unit price via bulk buying and Kirkland Signature substitution, with the warehouse club Everyday Low Price on multi-packs undercutting Walmart and Amazon on the same national-brand SKU at comparable pack size. Sam's Club and BJ's Wholesale compete in the same warehouse club category. For smaller weekly baskets or perishables that a household cannot finish before spoilage, Walmart or a regional grocer typically wins on total cost. Bulk buying works best when households have the storage, freezer space and consumption rate to clear a warehouse-club pack size before expiry.

Costco Gold Star is the standard consumer Costco membership at 65 US dollars per year (verify current pricing on costco.com), granting warehouse access, Costco.com ordering, Costco Travel booking and Costco Gas access at member pricing. Costco Executive Membership is the premium tier at 130 US dollars per year and adds a 2 percent annual reward on eligible Costco and Costco Travel purchases (capped at 1,000 US dollars per year), extra benefits on Costco Auto and Costco Services, and higher-tier terms on select Costco Travel packages. The Executive tier typically pays back for households spending above about 3,250 US dollars per year at Costco (the break-even point where the 2 percent reward covers the extra 65 US dollars in annual fee). The 100% satisfaction guarantee applies at both tiers. A new Costco membership sign-up at either tier started from the ShopBack Costco page earns cashback at the current published tier.

Costco Travel is Costco's member-only travel booking arm covering cruises, vacation packages, hotels, car rentals and theme-park tickets, with pricing set on a Costco member-exclusive basis rather than as a promo-code discount. Bookings settle at the Costco member rate with additional Executive Member benefits on select packages (a Costco Cash Card of a set value tied to package price, or bonus onboard credit on cruises). Costco Travel operates only for Costco members and is bookable at costcotravel.com or by phone. The 2 percent Executive Membership reward applies to eligible Costco Travel spend, capped at the 1,000 US dollar annual cap. A new Costco membership sign-up started from the ShopBack Costco page earns cashback at the current published tier, and Costco Travel becomes accessible on the same account.

For TVs (Samsung, LG, Sony, Hisense, TCL), laptops (HP, Lenovo, Dell), tablets, headphones, small kitchen appliances and gaming accessories, Costco is typically most aggressive during the monthly Costco Sale Book windows, the Black Friday event across late November, Cyber Monday Online-Only, and Post-Holiday clearance. Costco TVs and laptops often ship with an extended warranty (Costco's 2-year manufacturer warranty extension) plus Costco Concierge tech support, effectively adding value on top of the sticker price versus the same SKU at Best Buy or Walmart. For higher-end laptops and gaming consoles, Best Buy and Amazon US often compete hardest around Black Friday and Cyber Monday, so comparing the exact SKU across retailers is the reliable route. The 100% satisfaction guarantee applies to Costco electronics returns within the electronics return window.

All three are warehouse club retailers in the US with membership tiers, private-label ranges and bulk pack sizes. Costco typically wins on the Kirkland Signature range, Costco Travel, Costco Gas station pricing in most metros, and the 2 percent Executive reward economics for high-spend households. Sam's Club (Walmart-owned) typically competes hardest on Member's Mark private label, Scan and Go mobile checkout, and Sam's Club Plus tier free shipping. BJ's Wholesale operates primarily on the US East Coast and typically accepts manufacturer coupons on top of club pricing, which the other two do not, and competes on Berkley Jensen and Wellsley Farms private label. No single warehouse club is cheapest across the board on every SKU; the reliable saving strategy is to compare the exact bulk pack size on both club-brand and national-brand SKUs before renewing a membership. A new Costco membership sign-up from the ShopBack Costco page earns cashback at the current published tier. For a deeper look, see Costco Executive vs Sam's Club Plus vs BJ's Perks Rewards US 2026.

Costco operates two consumer membership tiers in the US: Gold Star at 65 US dollars per year (verify current pricing on costco.com) and Executive Membership at 130 US dollars per year. Both grant access to Costco warehouses, Costco.com, Costco Travel, Costco Gas, Costco Optical, Costco Pharmacy and Costco Hearing Aid Centers at Costco member pricing. Executive adds a 2 percent annual reward on eligible spend, capped at 1,000 US dollars per year, plus enhanced Costco Travel and Costco Services terms. Business Membership at the same base fee as Gold Star is aimed at resellers and small businesses and adds business-hours warehouse access. All tiers carry Costco's 100% satisfaction guarantee on membership and on most merchandise, with narrower return windows on electronics, appliances and diamonds. A new Costco membership sign-up started from the ShopBack Costco page earns cashback at the current published tier; renewals and upgrades are excluded per the rate panel.

Costco warehouses and costco.com share overlapping but not identical catalogs. Warehouse-only SKUs typically include fresh bakery, deli, meat, seafood, produce, cakes, hot rotisserie chicken, fresh flowers, Costco Optical fittings and Costco Hearing Aid Center appointments, plus certain single-warehouse clearance and treasure-hunt items. Online-only SKUs typically include larger appliances, furniture and bulk shipments where warehouse floor space is impractical, plus certain Costco Travel packages. Sale Book pricing usually applies at both, though some Warehouse Hot Buys are warehouse-exclusive. Costco.com typically carries a shipping fee on most orders (free on select big-ticket categories), while warehouse pickup is fee-free. New Costco membership sign-ups started from the ShopBack Costco page earn cashback at the current published tier, and both warehouse and online access follow membership activation.

Costco operates a 100% satisfaction guarantee on membership fees (refundable at any time on request) and on most Costco merchandise (returnable at any time with no fixed return window for the majority of the catalog). Narrower return windows apply to electronics (typically 90 days on TVs, computers, tablets, cameras, drones, projectors and major appliances), diamonds (1.00 carat and above require a Costco Diamond Guarantee card at return), cigarettes, alcohol where restricted by state law, tyres and batteries (limited-warranty terms), gold bars and silver coins, and custom-configured items. Returns are accepted at any US Costco warehouse regardless of purchase channel, or via Costco.com Return Center for online orders. Rejected, cancelled, refunded, exchanged or returned Costco membership sign-ups do not earn cashback per the ShopBack exclusion list.

ShopBack is a cashback portal in the US. Sign in at shopback.com, open the Costco merchant page above, and click through to the Costco new-membership sign-up flow in the same browser session. Cashback on Costco through ShopBack currently applies to new Costco membership sign-ups only (New Executive Membership and New Gold Star Membership) at the tiered rates published in the rate panel; regular Costco.com purchases and existing-member renewals or upgrades are excluded per the exclusion list. Clear cart, close the Costco app, accept all Costco cookies, and avoid adblockers, VPNs and third-party links to protect tracking. Any voucher or promo code not featured on ShopBack will block cashback on the sign-up.

Cashback stackability with Costco's own mechanics is conditional. ShopBack cashback on Costco is currently offered on new Costco membership sign-ups only (Executive and Gold Star tiers), so the primary stack question is with the membership itself: a new Gold Star or Executive sign-up initiated from ShopBack earns the published cashback rate on the sign-up fee, and Costco's own benefits (Executive 2 percent reward, Costco Travel member pricing, Costco Gas access, Kirkland Signature warehouse pricing, Sale Book events, 100% satisfaction guarantee) apply on the new membership going forward independently of the cashback. Renewals, tier upgrades of existing Gold Star, Business or Business Executive memberships, gift-card and voucher purchases, and any regular Costco.com order are excluded from cashback per the rate panel. Clear cart, close the Costco app, accept all cookies from Costco, avoid adblockers and VPNs, and verify tracking within the published 2-day tracked and 95-day confirmed windows.

Cashback typically applies to the initial Costco subscription sign-up when the click-through starts from the ShopBack Costco merchant page. Renewal charges billed on subsequent months usually do not qualify because they are not tied to a fresh affiliate click. Check the ShopBack Costco merchant page for the current subscription eligibility rule.

The cheapest way to get AirPods is usually to buy during a major retail sale event at a warehouse club or big-box retailer instead of paying list price at Apple. Costco members often see AirPods featured in the monthly Sale Book or holiday events, and Costco's electronics return window adds value beyond the sticker. Shoppers without a membership usually do best comparing Best Buy, Walmart and Target around Black Friday, Cyber Monday and back-to-school. Anyone who wants free engraving or AppleCare added at checkout may prefer Apple directly, and budget buyers can save more on the previous generation once a new model launches. Check the Terms section on the ShopBack Costco page to see what currently earns cashback and start from there before you sign up, and read our cheapest place to buy Apple devices guide for the full retailer comparison.

It often is for existing Costco members, because Costco tends to price Apple Watch below Apple's list price and adds Sale Book markdowns, though it stocks a narrower range of sizes, bands and finishes. If you need a specific case material, band or cellular configuration, Apple or Best Buy usually carries the full range. Non-members should add the annual membership fee to the comparison, which only pays off if you will also use Costco for groceries, household goods or other large purchases. First-time smartwatch buyers also benefit from Costco's electronics return window and member support. Check the Terms section on the ShopBack Costco page to see what currently earns cashback and start your membership sign-up there, and read our cheapest place to buy Apple devices guide for how Apple retailers compare.

Warehouse clubs like Costco and big-box retailers like Best Buy, Walmart and Target usually have the cheapest AirPods, especially around Black Friday, Cyber Monday and back-to-school sales, while Apple itself generally sells at list price. Costco suits members who already shop there and value its electronics return window. Best Buy suits shoppers who want open-box options, in-store pickup and a wide stock of every model. Walmart and Target suit shoppers who want quick pickup alongside a regular shopping run. If you want the newest model on launch day, Apple is the most reliable source, and if price matters most, the previous generation is usually the best value.
