Costco Code Checks, Day by Day

Every Costco code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many costco.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
7,846 automated cart runs412 shoppers reporting back

412 of these results came from shoppers telling us whether a code worked; the rest come from automated checks and the other sources above. Last confirmed working on . Codes that stop clearing get pulled off this page automatically.

What These Numbers Mean

A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means costco.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:

  • It expired or the store switched it off after it was published.
  • It was single-use and had already been redeemed.
  • It only covers certain categories, brands or individual products.
  • The cart did not reach a minimum spend.
  • It is limited to new customers, a first order, or an email sign-up.
  • It cannot be combined with an active sale or another code.
  • It is tied to a different country, currency or membership.

So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily Costco discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

  2. early January to late January

Before You Buy at Costco

What shoppers ask most about Costco.

›Can promotional coupon codes be stacked on Costco.com orders?

Costco generally does not support promotional code stacking on online transactions, restricting carts to a single active coupon code per checkout session. Specific warehouse savings items apply automatically without requiring code entry.

›Which product categories or brands are excluded from site-wide promo codes?

Promotional codes never apply to Kirkland Signature fuel cards, digital gift cards, or select major appliances from brands like LG and Samsung. These items are strictly exempt from third-party or promotional discount codes.

›How is membership eligibility checked for online promotional redemption?

Promotion codes and online checkout privileges require active membership verification tied to your account email. Guest checkouts incur a 5 percent non-member surcharge and cannot access member-exclusive promotional discounts.

›How does the Executive Membership annual 2 percent reward program calculate earnings?

Executive members earn an annual 2 percent reward on qualified Costco, Costco.com, and Costco Travel purchases, capped at a maximum of $1,250 per 12-month period. Purchases made prior to upgrading your membership tier are excluded.

How We Verify Costco Codes

Nothing goes up here on trust. A Costco code is collected, applied to a real costco.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

Help Other Costco Shoppers

Not every Costco code reaches us from the store. 9 codes on this page were first submitted by shoppers. They have also sent back 412 checkout results in the last 14 days, telling us which codes worked on a real cart and which came up empty. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

Have a code we missed?

Send it over and the agents will run it through a real costco.com cart. If it works, it lands here with the test behind it.

Did a code work for you?

Open any Costco code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
