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, so they might work for sandals but not sneakers.
The code required a certain cart value: Some promotions are only valid once you spend a certain amount.
The item you want is already on sale: Most discount codes don't stack and won't apply to items that are already on sale.
The code is expired: This can happen, as all coupons expire eventually. We do our best to keep track of expired coupons, but with so many shops online, it's a challenge! If you try using a code and find it's expired, please let us know, and we'll resolve it as quickly as possible.
