On my amazon account , I have a mastercard , but I would like to have an amazon gift card but in order to redeem a gift card from amazon , It's asking to claim the code I know if you have a amazon gift card you would have to scratch the peeling off to read the code ,I don't have neither the code or an amazon gift card , if anyone can give me some useful information , I would like to know how can you get more gift card codes from amazon?
