Several reasons could explain why your promo code didn't work:
1. The code may not be valid for the items you're trying to purchase. Some promo codes are specific to certain products, such as sandals but not sneakers.
2. The code might require a minimum cart value. Some promotions are only valid once you reach a certain spending threshold.
3. The item you want may already be on sale. Discount codes often cannot be applied to items that are already discounted.
4. The code could be expired. Coupons do expire eventually, and while we strive to keep track of expired coupons, there are many online shops. If you encounter an expired code, please let us know so we can address it promptly.
