I got GHWT from Asda - cost a tenner. Traded it in a week later for £9. £1 to play it and find out it was ****! I agree with Neal!
To be honest, I use Game and Gamestation a lot because, well, because I can't be titsed trying to sell my old games on eBay. So I use their trade in options a lot to get me cheap/"free" games while ditching stuff I haven't played for months and am unlikely to play (Sega Rally, I'm looking at YOU at the moment). Even if it's just a few quid, it gets rid of the things off my shelf.
However, sometimes the supermarkets just have offers too good though
