This is not a bad price if looking for the 4Gb XBox 360 with the Kinect included. This package is £249 everywhere else so a steal at this price if you are after one.
I bought an XBox 360 off Zavvi Ebay Outlet in October and it arrived the following day (Might not be the same for this one though due to the inclement weather conditions).
The new Xbox 360® 4GB Console. Here today, ready for tomorrow with a brand new, leaner machine. Wi-Fi is built in for easier connection to the world of entertainment on Xbox LIVE, where HD movies and TV stream in an instant. It’s ready for the controller-free experiences of Kinect—you don’t just play the game, you are the game. Xbox 360 is more games, entertainment, and fun.
