There are several reasons why your promo code may not have worked:
1. The code is not valid for the items in your cart: Promo codes are sometimes specific to certain products or categories, so they may not apply to all items.
2. The code requires a minimum cart value: Some promos are only valid once you reach a certain spending threshold.
3. The item you want is already discounted: Discount codes typically do not stack with existing sale prices.
4. The code has expired: Like all coupons, promo codes have expiration dates. If you receive a message that the code is expired, please let us know so we can address it promptly.
