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

where this data came from:
19 automated cart runs2 published by the store2 shoppers reporting back2 web search results
Shoppers who landed a working Casper code saved a median of $16.48 at checkout, about 7.96% off the cart. That comes from 2 real carts, comparing the total before and after the code was applied, not from an estimate.
2 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 casper.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 Casper 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 Casper
What shoppers ask most about Casper.
›Can promotional discount codes be combined with military or student offers?
Discount codes cannot be combined with other promotional offers or sitewide sales, and the total cumulative discount cannot exceed 35%. Additionally, verification through ID.me is required at checkout to apply identity-based savings.
›Are any specific product lines or categories excluded from promotional codes?
Promo codes and appreciation discounts exclude all final sale, clearance, and select newly launched mattress collections. Furthermore, items designated as clearance on the site are ineligible for price matching.
›Does Casper offer post-purchase price matching if an item goes on sale?
Price adjustments are honored if an item drops in price within 14 days of purchase on Casper.com. To claim a price match, customers must contact customer support with their order details for verification.
›How is eligibility verified for ID.me discount programs at checkout?
Eligibility for military, student, and healthcare discounts is authenticated instantly through ID.me during the online checkout flow. Once verified, a unique single-use code is generated and applied to the cart.
How We Verify Casper Codes
Nothing goes up here on trust. A Casper code is collected, applied to a real casper.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 Casper 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 Casper Shoppers
Not every Casper code reaches us from the store. 7 codes on this page were first submitted by shoppers. They have also sent back 2 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.
