There are several reasons why your promo code might not have worked:
1. The code isn't valid for the items in your cart: Some promo codes are specific to certain products, such as sandals but not sneakers.
2. The code required a minimum cart value: Some promos are only valid once you spend a certain amount.
3. The item you want is already on sale: Most of the time, discount codes cannot be used on items that are already discounted.
4. The code is expired: Occasionally, coupons expire. While we try to keep track of expired coupons, please let us know if you encounter an expired code so we can address it promptly.
