There are several reasons why your promo code may not have worked:
The code may not be valid for the items you're purchasing. Some promo codes are specific to certain products.
The code may require a minimum cart value. Some promos are only valid once you spend a certain amount.
The item you want may already be on sale. Discount codes often do not apply to items that are already discounted.
The code may be expired. Coupons expire eventually, and while efforts are made to keep track of expired coupons, some may slip through. If you encounter an expired code, please let us know, and we'll address it promptly.
