Been looking for a great deal on Kinect for a while now and this is easily the best I've seen, but it's only valid on Boxing Day. There are a few deals but the best two are easily:
Kinect w/ Kinect Adventures - £109.98
Kinect w/ Kinect Adventures, Kinect Sports and Dance Central - £154.98
You also get free express (next-day) delivery since the order's over £100 and you can get 1.5% if you do it through Quidco too.
Like I say though, the deal'll be gone tomorrow if GAME are to be believed.
Also you can add voucher code GAMESALE to the basket to get and extra £3.00 off (minimum spend of £30)
USE THE CODE "Perkz100" For £10 off to make it under £100
£10 code doesnt work anymore
