[quote name='SEH']When checking out, the credit will just be applied. If you try to check your account/gift card balance or whatever, it'll show $0.00. It's dumb, but that's just how it works.
Also, make sure you buy something worth at least the full amount of credit you have. It doesnt work like you think it would where say you have a $20 credit and you buy a $15 item. You wont still have $5 in credit after your purchase.[/QUOTE]
Hmm, when I got my PS3 back on cyber monday that's exactly how the credit I got worked and it did show up on the gift card balance, though strangely the multiple $5 mp3 credits I've gotten have never shown up on it.
To my knowledge, Amazon hasn't shipped/applied/whatever the credit for any of the rdr preorders yet, they've been saying sometime between the 27th and 30th at the latest when I've contacted them.
