Bought one of these here online this site last year after having got burned on ebay by a seller who sold me a fake code, and kept my money. Then I came here to this site, and got my key in no time. Just buy the code, verify if its your first time buying, and they send you the key in email & put it here on your account as well.
Why buy XBox Gold? Well for one you get free games each month for both 360 & One. If you do not have a hard drive or a console you can still get the games free 2x a month via a web browser which is what I have been doing as my 360 died 3 days after I got my card lol. Wasnt really funny, but at least it wasnt a complete loss.
Buy your codes here. With Amazon they take to long, and with other sites they either take a long time making you jump threw hoops or you have to wait for the game card to show up in the mail. Here you pay, you verify, and you get your key. Fast, easy, secure, and simple.
