so HMV at the moment are doing kinect with joy ride / sonic for £144.99, I was in a branch of HMV yesterday and got chatting to a sales guy and said i was looking for one but did not want those games. Short story is HMV will change the two games for any two other games of the same value. £39.99 and £44.99 respectively.
Today i went to my local gamestation and mentioned this and they instantly price matched it. so i got kinect with adventures, dance central, and sports for the same price. to top that they also had some old stock games saying 19.99 when bought with any kinect bundle, so i got those as well all on store credit by price matching CEX. May be of use to some of you out there.
