This might be an error, I'm not certain, but worth a try if you're after the xbox 360 premium. It's says it's the xbox 360, but the description shows it as a premium, with the hard drive, wireless controller and the headset!!!
EDIT - Members have confirmed this is the core machine, but it comes with all the extras mentioned below, which TECHNICALLY make it the premium pack. If you aren't happy when you receive it, you can return it for free anyway. BUY-NOW-THINK-LATER!
