I was looking into Buzz games for xmas and found PC WORLD online sellling these for a great reduction at £19.97 (from £34.99) for reserve and collect. I was about to pay nearly this for controllers alone. They also have the mega quiz available at £14.97.
You have to do the usual search and hope you find one close enough to you to make the deal feasible. However, it took the staff 2 hours to locate my reserved items. They were hidden away (as usual) in the safe store.
