Coupons can be added to the cart page or checkout page by clicking the link that says "Have a gift card or coupon code?".
Coupons can only be used on full-priced orders and do not apply to shipping costs. If you're having trouble using a coupon you've received, it could be that the code is invalid, the coupon is not for our site, or the items don't qualify for additional discounts. If you have any questions about a coupon code you have, feel free to reach out to us.
