There are several reasons why your promo code might not work:
1. The code isn't valid for the items you've selected: Some promo codes are specific to certain products or categories.
2. The code requires a minimum cart value: Some promos only apply once you've spent a certain amount.
3. The item you want is already discounted: Often, discount codes cannot be used on items that are already on sale.
4. The code has expired: Coupons do have expiration dates, and if a code is expired, it will not work. We strive to keep track of expired coupons, but with the vast number of online shops, some may slip through. If you encounter an expired code, please let us know so we can address it promptly.
