Coupon codes give you access to limited-time offers and discounts. In order to receive your discount, you will need to input your coupon code at the end of the checkout process. Under Step 5: Order Confirmation, you will find a text input field for ‘Gift Certificate or Coupon Code’.
This is where you will enter your coupon code (for example: “CODE-01”). Click “Apply”. Your subtotal will now be updated with the discount applied. You can proceed to check out as normal.
