A Costco promo code is a discount code that can help eligible shoppers save on qualifying orders, receive membership rewards, or unlock special promotions. Costco offers different types of deals, including online order discounts, SameDay delivery offers, and new membership incentives such as Digital Costco Shop Cards.
One of the listed offers is SUMMERSAMEDAY26, which provides eligible Costco members with $10 off a $35+ SameDay.Costco.com order when the promotion requirements are met. Another membership-related offer is AFFNMBR, which provides a $40 Digital Costco Shop Card for qualifying new Costco members under the promotion terms.
Costco promo codes are not always available for every shopper because many offers have specific conditions, such as membership requirements, minimum purchase amounts, eligible products, delivery areas, or expiration dates. The tables below include Costco promo codes, membership deals, and additional coupon offers with details to help shoppers understand how each promotion works.
Current Costco Promo Codes, Coupons & Savings
Costco offers different types of promotions, including online promo codes, membership incentives, Digital Costco Shop Cards, SameDay delivery discounts, and product-specific savings. The codes below include the Costco offers provided for this article, along with their advertised discounts. Some are third-party listings, so their availability can change and should be confirmed at checkout.
| Promo Code | Discount / Offer | Type / Information |
|---|---|---|
| SUMMERSAMEDAY26 | $10 off $35+ | SameDay Costco order |
| AFFNMBR | Free $40 Digital Costco Shop Card | New membership offer |
| GOLDEN | $50 Digital Costco Shop Card | New membership offer |
| EBGCOST | Up to $0.01 off | 1-year membership offer |
| COSTX | Up to $0.01 off | Online promo |
| CWS25 | Free $0.01 Costco Shop Card | Third-party listing |
| BRADSDEALS | $0.01 off | Costco savings offer |
| CJSLICK | $0.01 off membership | Membership offer |
| CJPROMO | $50 Digital Costco Shop Card | Membership + auto-renewal |
| LIMIT 1 | Up to $10 off | Online order offer |
| VBS25 | Up to 25% off | Selected Costco products |
| USFB08C | Up to 30% off | Selected Costco products |
Among these offers, SUMMERSAMEDAY26 is different from a standard Costco.com coupon because it is tied to SameDay.Costco.com. Membership promotions such as AFFNMBR, GOLDEN, and CJPROMO are also not ordinary checkout discounts; they provide a Digital Costco Shop Card when the stated membership requirements are met.
Codes such as EBGCOST, COSTX, CWS25, BRADSDEALS, CJSLICK, LIMIT 1, VBS25, and USFB08C were supplied as third-party coupon listings. Their presence on a coupon website does not guarantee that Costco currently accepts them. If a code does not work, check its restrictions, expiration date, membership requirements, and eligible products.
Total Wine & More Promo Codes
The following codes belong to Total Wine & More, not Costco. They can be included in a broader coupon section, but they should remain clearly separated from Costco offers.
| Promo Code | Discount / Offer | Type / Information |
|---|---|---|
| DELIVERY99 | Free delivery on $99+ | Delivery offer |
| RELATE | $5 off | Order discount |
| DELIVERY49 | Free delivery on $49+ | Delivery offer |
| SHIPFREE | Free shipping on $99+ | Shipping offer |
| SHIPPING99 | Free shipping | Shipping offer |
| DELIVERYDM | $5 off | Delivery promotion |
| DELIVERY99CA | Free shipping | Qualifying purchase |
| FIREWORKS10 | 10% off | Purchase discount |
| SPRING15 | 15% off | Purchase discount |
| 1799 | 10% off | Order discount |
| 1768 | 5% off | Order discount |
| 1771 | 15% off | Order discount |
| 1767 | Up to 10% off | Order discount |
| DELIVERY99WD | Free shipping | Shipping offer |
| SHIPWINE | Free shipping | Shipping offer |
| 1320 | Up to 5% off | Purchase discount |
| GOBBLE10 | 5% off | Order discount |
| JOLLY10 | 10% off | Purchase discount |
When using any coupon, check the retailer’s checkout page for the actual discount before paying. Minimum order values, eligible products, membership status, delivery areas, expiration dates, and other restrictions can affect whether a code works. This is especially important for third-party coupon codes, which may remain listed online after a promotion has ended.
Costco Promo Code $50 Off $500: Is It Available?
There is no verified Costco-wide $50 off $500 promo code that should be presented as a current general coupon.
Some coupon websites and deal pages may advertise $50-off offers, but a large discount shown on a third-party coupon page does not mean Costco currently accepts that code. Costco promotions are often tied to specific products, membership offers, partner programs, or limited checkout campaigns.
For that reason, shoppers should check the promotion’s terms and make sure the discount actually appears in the Costco checkout before placing an order.
Costco Promo Code for Membership in 2026
Costco promo codes are often used for membership promotions instead of regular shopping discounts. These offers usually help new members get extra value through rewards such as Digital Costco Shop Cards rather than reducing the membership fee directly.
A previous membership offer used the code GOLDEN, which provided a $50 Digital Costco Shop Card for eligible new Costco members. The promotion was designed for shoppers joining Costco for the first time or members whose previous membership had been inactive for the required period.
Membership promotions like this usually include specific conditions, such as eligibility requirements, auto-renewal enrollment, and a limited redemption period. Because of these rules, a promo code may appear on coupon websites even after Costco has stopped accepting it.
Before using any Costco membership promo code, check the latest offer details, eligibility rules, and redemption requirements on Costco’s official membership page to make sure the deal is still available.
Costco Promo Codes From Coupon Sites and Reddit
Reddit and coupon websites can be useful for discovering promotions, but they should not be treated as proof that a code is currently valid.
For example, Costco shoppers have discussed membership codes such as SPRING26 on Reddit, but that particular promotion was reported as valid only through May 10, 2026.
The same issue applies to codes such as EBGCOST, COSTX, CWS25, BRADSDEALS, CJSLICK, and CJPROMO from the supplied coupon list. These codes should be treated as unverified or expired unless Costco’s checkout or an official Costco promotion confirms them.
A coupon page can continue indexing an old code after Costco has stopped accepting it.
Costco Promo Code Free Shipping
Costco occasionally offers free shipping promotions on selected products, but there is usually no universal free shipping promo code for all orders. Shipping benefits often depend on the item, membership type, order value, and current Costco promotions.
Before completing a purchase, check the product page and checkout section to see if free shipping is available for your order. Some Costco items may include shipping in the listed price, while others may have separate delivery charges.
Costco Promo Code $100 Off $500
The same caution applies to claims about a Costco promo code for $100 off $500. There is no current Costco official source confirming a general $100-off-$500 coupon for all shoppers.
Costco does regularly run large product-specific Instant Savings offers. For example, its current warehouse savings page lists individual products with discounts such as $50, $60, and $100 off during specified promotional periods. Those are product promotions rather than a universal $100-off-$500 promo code.
If you see a $100-off-$500 code on a coupon site, check whether it is restricted to a particular product category, account, membership offer, or partner.
Costco Promo Code for Appliances
Costco does not normally require one universal coupon code for appliance savings. Instead, appliance discounts may appear as Instant Savings, product promotions, Costco Shop Card offers, or limited-time online deals.
Before buying a major appliance, check:
- The product’s current sale price.
- Any Instant Savings attached to the item.
- Costco Shop Card promotions.
- Delivery and installation terms.
- The promotion’s start and end dates.
- Whether the offer applies online, in warehouses, or both.
This approach is more reliable than searching for a generic appliance promo code because Costco’s product promotions can change independently.
How to Use a Costco Promo Code
The redemption process depends on the promotion. For the current SameDay offer:
- Sign in to your Costco membership account.
- Shop through SameDay.Costco.com.
- Build an eligible order of at least $35.
- Continue to checkout.
- Enter SUMMERSAMEDAY26 in the promo-code field.
- Confirm that the $10 instant credit appears before completing the order.
The offer is limited to one use per valid membership and cannot be combined with another offer. Costco says the promotion is available in the United States, excluding territories, subject to product and delivery availability.
Costco Membership Deals You Can Still Check
Even when a specific promo code expires, Costco continues to run membership incentives.
Costco’s current membership information shows regular annual membership pricing of $65 for Gold Star and $130 for Executive, plus applicable sales tax. Costco also periodically offers Digital Costco Shop Cards to qualifying new members.
Another current option is Costco’s Refer-a-Friend promotion. Costco says that when an eligible existing member refers a new member and the requirements are met, both can receive a Digital Costco Shop Card. The listed reward is $40 with an Executive Membership or $20 with a Gold Star Membership, with the offer scheduled to expire December 31, 2026.
The referral promotion has its own requirements, including auto-renewal and eligibility rules, so it should not be treated as a universal Costco coupon.
Does Costco Have $50 or $100 Shop Card Offers?
Yes, Costco does use Digital Costco Shop Cards as promotional incentives, especially for memberships and selected purchases.
A Shop Card is different from an instant coupon. Instead of reducing the price at checkout, the promotion provides a card with a specified value under the promotion’s terms. Costco maintains a dedicated Shop Card FAQ covering Digital Shop Cards, balances, redemption, and related questions.
That distinction matters when comparing a “$50 Costco discount” with a “$50 Costco Shop d.” They are not necessarily the same type of savings.
Why Some Costco Promo Codes Do Not Work
A Costco code may fail because:
- The promotion has expired.
- The code is for SameDay.Costco.com rather than Costco.com.
- You are not eligible for the membership promotion.
- Your order does not meet the minimum purchase requirement.
- The promotion is limited to selected products.
- Your delivery area is not eligible.
- The code cannot be combined with another offer.
- The code has reached its usage limit.
For the current SUMMERSAMEDAY26 promotion, Costco specifically requires a $35 merchandise minimum and limits the offer to one use per membership.
Costco Promo Code FAQs
What is the Costco promo code for $10 off $35?
SUMMERSAMEDAY26 provides $10 off a qualifying $35+ SameDay.Costco.com order. The official promotion ends August 23, 2026, and has additional eligibility requirements.
Is SUMMERSAMEDAY26 valid on Costco.com?
No. Costco’s terms state that this promotion is available only through SameDay.Costco.com, not the regular Costco.com shopping site.
Is GOLDEN still a valid Costco promo code?
No. The $50 Digital Costco Shop Card promotion associated with GOLDEN was listed by Costco as valid through August 2, 2026.
Does Costco have a $50 off $500 coupon?
There is no verified general Costco $50-off-$500 coupon that should be treated as a current nationwide offer.
Does Costco have a $100 off $500 promo code?
There is no verified current Costco-wide $100-off-$500 code. Costco instead frequently uses product-specific Instant Savings and other targeted promotions.
Can Costco promo codes be used with other coupons?
Not always. Each promotion has its own terms. For example, Costco’s current SameDay offer cannot be combined with another offer.
Where can I find legitimate Costco coupons?
Start with Costco’s own website, membership promotions, Instant Savings pages, and checkout. Third-party coupon sites and Reddit can help identify potential deals, but the code should be confirmed through Costco before relying on it.
Final Takeaway
The most clearly verified Costco promo code for August 23, 2026 is SUMMERSAMEDAY26, offering $10 off a qualifying $35+ SameDay.Costco.com order. It is a limited-time delivery promotion and expires at the end of August 23.
Older codes such as GOLDEN may still appear online, but Costco’s official page shows that the $50 membership promotion ended August 2. For larger claims such as $50 off $500 or $100 off $500, verify the offer at Costco checkout instead of assuming a third-party coupon listing is current.
