There are a few reasons why your promo code might not have worked:

• The code isn't valid for your items: Sometimes promo codes are product-specific, where maybe it would work for sandals, for example, and not sneakers.
• The code required a certain cart value: Some promos also are only valid once you spend a certain amount.
• The item you want is already on sale: Most of the time, discount codes don't stack and apply to items that are already on sale.
• The code is expired: Yes, sometimes this does happen, as all coupons expire eventually. We do our best to keep on top of expired coupons, there are a lot of shops online though! If you try using a code and you get the response that it's expired, please do let us know and we'll get it sorted as quickly as we can.
