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

where this data came from:
11 web search results5 shoppers reporting back2 automated cart runs1 tracked orders
5 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 case-mate.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 Case-Mate 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 Case-Mate
What shoppers ask most about Case-Mate.
›Do discount codes apply to collaboration lines?
Promo codes never apply to collaboration items, which feature partnered brands like Coach and Kate Spade New York. These items are strictly designated as final sale.
›Can I combine multiple promo codes on a single order?
Only one promotional code or coupon can be redeemed per checkout transaction. Stacking multiple discounts or coupons is automatically blocked by the cart system.
›What happens if I need to return a bundle purchase?
Bundle returns must be sent back in full with all original products included. Partial returns for individual items from a promotional bundle are not accepted.
›Are original shipping fees refunded on returned items?
Original shipping charges and package protection fees are strictly non-refundable upon return. Customers receive product-only refunds back to their original payment method.
How We Verify Case-Mate Codes
Nothing goes up here on trust. A Case-Mate code is collected, applied to a real case-mate.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 Case-Mate 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.
Help Other Case-Mate Shoppers
Not every Case-Mate code reaches us from the store. 8 codes on this page were first submitted by shoppers. They have also sent back 5 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 case-mate.com cart. If it works, it lands here with the test behind it.
Did a code work for you?
Open any Case-Mate 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.
