I just found yakuza 2 for the PS2 to be on pre order for £14.99 i checked other stores and amazon is doing the same price and game is selling it for £24.99 online.
This game comes out Friday 19th September and am sure you cant find it cheaper than £15. Yes i know it was realeased in japan about 2 years ago, but its finally coming to europe now. I checked to see if there were any posts on this and none appeared. Be my guest if you find any posts about this already.
Edit: Hmv is selling for £29.99 online
Gamestation doesnt have it on their database online yet.
zavvi online has it for £17.99.
Woolworths online has it for £16.99
All these prices are online only, not instore. Instore is bound to be more expensive.
