How do I use a promo code? Follow

To apply a promo or discount code to your order, enter the code at checkout once you've added items to your cart. 

If you have received a special code, it must be entered before the shipping information page. We are not able to apply a code to an order that has been completed. If you are on the Shipment or Payment page, please go back to the Cart page to enter your code before completing the checkout.

Please note, only one promotional or discount code can be used for an order.
