A publisher can provide you with a coupon code to offer you a discount on a future purchase. Coupon codes apply to specific products defined by the publisher and typically consist of a sequence of letters and numbers.
After selecting your payment type in your online order, enter your valid coupon code in the field labeled "Your coupon code". Your coupon is applied after you have completed entering your data and have been redirected to the next order process page.
If you place your order with our customer service, please enter your coupon code in addition to your other information so we can apply the coupon to your order.
