There are several potential reasons why your promo code may not have worked:
1. The code isn't valid for the items in your cart: Sometimes promo codes are specific to certain products or categories, so it might work for sandals but not for sneakers, for example.
2. The code requires a minimum cart value: Certain promotions are only valid once you've spent a certain amount.
3. The item you want is already on sale: In many cases, discount codes cannot be used on items that are already discounted.
4. The code has expired: Like all coupons, promo codes have expiration dates. While we strive to keep track of expired codes, occasionally one may slip through the cracks. If you find that a code has expired, please let us know so we can address it promptly.
