This is what I know: Here's how to apply it: Shop your favorite brands at up to 90% off estimated retail. Add items to your cart and checkout. Click on APPLY A GIFT CARD and enter your card number and pin. If your purchase exceeds the amount on your gift card, you’ll have to add an additional form of payment. If your purchase is less than the amount on your gift card, you’ll have a remaining balance.
BTW to answer comments just hover over the comment box, and hit the reply button. Just making another comment doesn't let the person know you've replied without checking back to the listing ;)
