This is a relist of one that got expired earlier in week (this time I'm only listing it as available in York)
HMV in York are promoting a £299.99 bundle that includes any 3 chart games priced up to £39.99. If you buy a game priced more than that they'll just charge you the difference.
If you haggle with the sales staff they'll let you substitute stuff like extra controllers or blu ray remotes (in general it seems to be get three things worth £120 for free)
This got expired last time due to lack of evidence and nationwide availability, but I reckon HMV are up to a bit of haggling. I've took some pics
