When i first signed up for xbox live, i got the standard 1 month free but After that i wasn't sure i wanted to make the commitment for monthly payments coming out of my bank. Now i have another option, i get one of these cards every 3 months so if i'm not playing it as much after 3 months i can wait a while before getting the next card without money being taken from my account; and it's atcually cheaper to buy these cards than it is to pay for 3 months of xbox live on direct debit.
Just dont do what 2 of these reviewers did and buy this thinking it will work with the origional xbox, this is xbox 360 only! And those two didn't really rate the product, they just rated their own stupidity when they gave it 3 stars.
I'm Gamertag Teris IXI, feel free to find me on Xbox Live.
