There could be several reasons why your promo code didn't work:
The code may not be valid for the items you're purchasing. Sometimes promo codes are specific to certain products.
The code might require a minimum cart value to be applied. Certain promos only work once you reach a certain spending threshold.
The item you're interested in could already be on sale. Often, discount codes cannot be used on items that are already discounted.
The code may have expired. Coupons have expiration dates, and while we strive to keep track of expired codes, some may slip through the cracks. If you encounter an expired code, please let us know, and we'll address it promptly.
