At checkout, under payment method, please select “Use gift card” and enter your 16-digit card number along with your 8-digit pin code and select “Apply Gift Card”. 

If the card balance is insufficient to cover the purchase amount, we will ask you to enter an additional payment method. 

If the purchase amount is less than the gift card balance, the unused balance will remain available for you to redeem on your next purchase. In the same way, you can redeem multiple gift cards on a single purchase.
