When you place an order, you will see a box on the checkout page where you can enter your promo code. After you click "Apply Coupon", the promo code will be applied and discount will appear immediately along with your order total. The promo code must be redeemed at the point of ordering process; we are unable to apply the promo code after the order has been processed. Only one promo code can be used per purchase. Please note that you will not be able to use a promo code as the only mode of payment for your order. The cost of the order must exceed the cost of the promo code and a credit card must be provided.
