If you have a discount code, you can enter it on the checkout page where you enter your shipping address and payment information (see image below). If you're paying via Paypal, after authorizing your account you will be returned to this page and can enter the discount code. Discount codes typically only work with one-time purchases. They sometimes work on the first order of a subscription. However, they DO NOT work with ShopPay auto-installments.Only one discount code can be used per order and they typically cannot be combined. So for example, if you're using reward points to pay for part of your order, you can't use another discount code on top of that.The only exception is that sometimes a product discount can be combined with a shipping discount, such as on an occasion that we might offer a free shipping promo. (Also note that U.S. orders of $100 or more automatically get free shipping, and you CAN use a discount code in addition to that.)BELOW IS AN EXAMPLE OF OUR CHECKOUT PAGE, WITH THE DISCOUNT CODE BOX TO THE RIGHT:
