There are several reasons why your promo code might not have worked:
The code isn't valid for your items: Some promo codes are product-specific, meaning they might work for sandals but not sneakers.
The code required a certain cart value: Some promos are only valid when you spend a certain amount.
The item you want is already on sale: Discount codes usually don't stack with items that are already on sale.
The code is expired: Coupons do expire eventually. We do our best to keep up with expired coupons, but with so many shops online, it can happen. If you try using a code and find it's expired, please let us know, and we'll address it as quickly as possible.
