Note: On Quidco, it seems to say the 10% voucher expires at midnight 31st October whereas voucher page here says 30th October.
This is the cheapest by far that I've found at the moment. I tried looking at Amazon, Zavvi, HMV, Game, and Play, others are at around £29.99 mark.
"Football Manager 2009 is set to feature a vast array of all new features including, for the first time ever, a full 3D view of the world famous Football Manager match engine. Football Manager Handheld 2009 for Sony PSP is also set for release on the same day and see the debut of a 2D match engine for the handheld franchise.
The Football Manager match engine is being brought into full 3D with motion captured animations for each player, developed in conjunction with SEGA's in-house studio, Sports R&D Division. You can now watch your matches in 3D from multiple camera angles, and can re-watch any part of the match by fast forwarding and rewinding the action using a new match time bar that flags the key moments in the game. There is also a new full screen TV view, where players can customise their match view by choosing the information they would like to view during the match, be it the latest scores or player performance stats for the match, and arranging this information onscreen using a new drag-and-drop widget system, that lets players customise their match day screen with the information that they need as a football manager."
