Went into Gamestation Perry Barr yesterday and got them to price match the Asda £79 deal which they did. I had a Gamestation points card which they gaveme £12 worth points as well. Not sure how long the points promotion is on for. Works out to about £67.
Note - You must be instore at the time when the sales assistant phones Asda to check stock availability.
Cracking deal. Got Kinect Sports from HMV online with the 20% off code for £27
