Wanted the new Xbox Kinect so have been looking at the best deals on at the moment. Most shops not giving much away deal wise so went for this at Argos.
Buy the Kinect on it's own (also comes with Kinect Adventures game) for £129.99 and you get £10 off for spending over £100.
Then bought Dance Central for £30.99, used £10 off voucher so got it for £20.99.
Do it in two transactions rather than buying all at once to get this deal. Will obviously apply to whatever game you want.
Best I saw this in the other stores was £169.99
