Very easy. First sign in and click on menu, then order status/account, then scroll down to view my gift cards. That will show your gift cards with how much is on it. They will have codes you just have to copy and enter during checkout. Hope this helps.

David, click on 'Order Status/Account" at top of page. Scroll down to where it says
'Gift Cards
View and email my gift cards View and email my gift cards' and click on that, you will see your gift cards. You can copy & paste the number at checkout to redeem it. Have a great day!
