Be careful if you are using gift cards to pay for their merchandise. I had a problem over the weekend and the rep. said that in most cases, the charge card is being used over the gift cards. (it should be the other way around)
When I called this morning to see if they had fixed the problem (to reorder) the rep said it was hit or miss. If you don't see your gift card deducted in the second to last screen, then it has not been used.
