Why the share is low: code checks are run against real carts, including plenty this code was never eligible for. Most codes only apply to certain products or need a minimum cart, so a working code still fails on every cart it never fit.

where this data came from:
123 automated cart runs19 shoppers reporting back3 web search results

Shoppers who landed a working COS code saved a median of $19.82 at checkout, about 12.75% off the cart. That comes from 12 real carts, comparing the total before and after the code was applied, not from an estimate.

19 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.

Why the success rate is low: checks run on real carts, and most codes only apply to certain products or above a minimum spend, so a working code still fails on every cart it never fit. A low rate means the codes are picky, not that none of them work.

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 cos.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 COS 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.

Before You Buy at COS

What shoppers ask most about COS.

›Do COS promo codes work today?

Likely. A code listed here last took money off a real COS cart today. 1 code also rates well on our checks.

›Can promotional codes be combined with other offers or sale items?

Promotional codes cannot be combined with any other offers or active discounts. Student discount codes are restricted to specific terms and may apply to selected full-price lines only.

›Are there specific items excluded from promotional discount codes?

Standard promotional codes exclude gift cards, selected designer collaborations, and specific limited-edition capsule collections. Always check specific campaign terms for brand exclusions.

›How is student discount eligibility verified at checkout?

Student verification is processed securely through Student Beans, issuing a single-use code to apply in your online shopping bag. The account email must match your active student profile.

›Does COS offer price adjustments if an item goes on sale after purchase?

COS does not offer retroactive price adjustments for items purchased prior to the launch of a seasonal markdown or promotional event.

How We Verify COS Codes

Nothing goes up here on trust. A COS code is collected, applied to a real cos.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.

The agents keep retesting every COS code on this page. No one here vouches for a code they did not watch work. If one slips through expired, take the next on the list. We keep backups. Want more codes we have watched work? See top-rated verified promo codes from every store.

Help Other COS Shoppers

Not every COS code reaches us from the store. 7 codes on this page were first submitted by shoppers. They have also sent back 19 checkout results in the last 15 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.
