There are several possible reasons why your promo code might not have worked:
- The code may not be valid for the items in your cart. Some promo codes are specific to certain products or categories.
- The code might require a minimum cart value that you haven't reached yet. Some promos only apply once you spend a certain amount.
- The item you want to purchase could already be on sale. In many cases, discount codes cannot be applied to items that are already discounted.
- The code could be expired. Coupons have expiration dates, and if the code has expired, it will no longer work.
