You dont even need a card to get these deals. All a person needs to do is goto http://xboxlivediamond.com/ and put in anyones gamertag (if you dont have one) And there you have it! The same great deals. As for the ones that say you need to show your card, well I did it without a card. The card has no numbers or anything on it. Plus it has a spelling error. Take a look!
