There are several potential reasons why your promo code may not have worked:
1. The code is not valid for your specific items: Some promo codes are item-specific, meaning they may work for one product but not another.
2. The code requires a minimum cart value: Certain promotions are only valid once you reach a certain spending threshold.
3. The item you want is already discounted: In many cases, discount codes cannot be used on items that are already on sale.
4. The code has expired: Like all coupons, promo codes have expiration dates. If you receive an expired code message, please let us know so we can address it promptly.
