To redeem a promo code, go to your shopping cart, and scroll down to where it says Apply Promo Codes. Enter your email address, wait for the shopping cart to reload, and then enter your promo code.
You can only use a promo code once and only one promo code per item. To use a newsletter promo code, you must be subscribed for at least 24 hours. Unless otherwise stated, a promo code will work on up to 5 of the same item if they are all in one order.
