There could be several reasons why your promo code didn't work:
1. The code may not be valid for the items in your cart. Some promo codes are specific to certain products, so they might work for sandals but not for sneakers, for example.
2. The code might require a minimum cart value. Some promos are only applicable once you reach a certain spending threshold.
3. The item you're trying to purchase may already be on sale. Often, discount codes cannot be used in conjunction with items that are already discounted.
4. The code may have expired. Coupons typically have expiration dates, and despite our efforts to keep track of expired codes, it's possible that one slipped through the cracks. If you encounter an expired code, please let us know, and we'll address it promptly.
