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

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 castore.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 Castore 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.
When Castore Runs Sales
Recurring events worth timing an order around. Windows shift year to year, so treat them as a shopping calendar rather than a fixed date.

- late December to JanuaryEnd of Season Clearance
Deep markdowns on seasonal activewear lines with discounts reaching up to seventy percent off.

Before You Buy at Castore
What shoppers ask most about Castore.
›Can promotional codes be combined with sale items?
Promotional codes cannot be stacked with items already marked down in the sale section. Each discount code applies exclusively to full-priced merchandise unless a special site-wide clearance event explicitly states otherwise.
›Are any product lines excluded from coupon codes?
Standard promotional codes exclude gift cards and select limited-edition partner team kits. These restricted items will prompt an error message at checkout if a code is applied to them.
›How do key workers redeem their healthcare discount?
Key workers must verify their employment status through Gocertify at checkout to receive a single-use discount code. The verification code is tied to your personal email address and cannot be transferred.
›Does Castore offer post-purchase price matching?
Castore does not offer retroactive price matching if an item goes on sale after your purchase. However, unworn items within the 28-day return window can be returned for a full refund.
How We Verify Castore Codes
Nothing goes up here on trust. A Castore code is collected, applied to a real castore.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.
