There are several reasons why your promo code might not have worked:
1. The code isn't valid for the items you're purchasing: Some promo codes are specific to certain products, such as sandals but not sneakers.
2. The code requires a minimum cart value: Some promos are only valid once you spend a certain amount.
3. The item you want is already on sale: Discount codes typically don't stack with items that are already discounted.
4. The code has expired: Coupons have expiration dates, and while we try to keep track of expired codes, some may slip through. If you encounter an expired code, please let us know so we can update it promptly.
