If you received a special promotional code by email (with the code shown in the email), these generally cannot be combined with any other offer or deal. Deals are only valid on new orders after the deal has been published – no, you cannot get a discount on an order placed prior to the deal being launched. Once a deal expires, it is expired. If your coupon code does not qualify it will not work, but in the instance it does and its not working simply enter it in notes and we will investigate when we receive the order. *PRE-ORDERS ARE NOT ELIGIBLE FOR ADDITIONAL PRODUCT GIVEAWAYS OR COUPON CODES.
