Hi, just before Xmas one of my friends completed one of these free Xbox 360 schemes and he actually received his console. After his success I decided to give it a try. Apparently you just have to sign up to the DVD rental website and cancel it straight away. So I've been told. After that you get some friends to do it and you get your stuff. The good thing about this website is that you can get some good accessories for only 2 referrals which is good and some people might be interested in if they already have a 360. If you want to give it a try go to: http://360.online-giveaway.co.uk/?r=41.
I know most people think that this probably doesn't work, but I'm pretty sure it does as I've seen the end product :D.
