Several reasons could explain why your promo code didn't work:
1. The code might not be valid for the items in your cart: Some promo codes are specific to certain products, like sandals instead of sneakers.
2. The code might require a minimum cart value: Some promos only apply once you've spent a certain amount.
3. The item you want may already be on sale: Often, discount codes don't stack with items already discounted.
4. The code might be expired: Coupons do expire, and while efforts are made to keep track of this, some may slip through. If you find an expired code, please let us know, and we'll resolve it promptly.
