Basically, it's a way to get free Xbox Live trials. I'm not so sure the stipulations, but I'm pretty sure there are no strings attached. Give it a whirl, see how it goes.
Apparently it works, so say's my friend.
they had x-box live trials in my local shopping mall recently, i got chatting to the promoters and they gave me a free xbox live shirt :D
Id wear the shirt too!!!
