First post, so be kind. I've been creaming off everyone's deals here for a while, so thought I'd share this.
I was looking through the pre-owned PS3 games in GAME Oxford Street, and found they are selling both Pro Evolution Soccer 2009 and FIFA 2008 for just 99p. As has been pointed out, Fifa is available for 75p pre-owned at CEX apparently, but unless anyone can tell me different, that's good for PES 2009.
They may not be the newest, but they are both still great games. At 99p, you can't go wrong!
I don't know if this is store specific, but online they are both £3.99.
