Once you have added all your items to your cart click on the shopping cart icon at the top right of the page. Add your Gift Card number into the 'Gift Card Number' field just above the 'Check Out' button toward the bottom right of the page. NOTE: If there is a shipping fee to pay you will need to use some other method (credit card, PayPal, etc.) to pay for this as the gift card redemption happens prior to the shipping fee being calculated.
