I don't know if anyone else has said this yet... I recently went ahead and bought 2 of the flaming helmets from BestBuy.com and I couldn't have more than 1 "helmet" in my shopping cart at once. I HAD to do separate purchases to get more than 1.
So if that affects how you use the gift cert, I'd keep that in mind. I used my credit card, but I don't remember if certs are like gift cards.
