Here are a few possible reasons why your promo code may not have worked:
The code may not be valid for the items in your cart. Some promo codes are specific to certain products, meaning they might work for sandals, for instance, but not sneakers.
The code might require a minimum cart value. Certain promos are only applicable once you've spent a certain amount.
The item you're interested in may already be on sale. Generally, discount codes don't apply to items already discounted.
The code may have expired. Yes, this does happen sometimes, as all coupons eventually expire. While efforts are made to stay updated on expired coupons, there are numerous online shops. If you attempt to use a code and find it's expired, please inform us, and we'll address it promptly.
