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.
