Visited Gamestation today and noticed they had the following PS3 games priced at £2.99.....
Pro Evolution 2008
Tiger Woods 2007
(All were Pre-owned but plenty left on the shelf).
Might be worth checking your local store... sounds like prices are national.
P.S. (These prices were in Scunthorpe store)
Update: Perfect Dark Zero also available (in Weymouth store)=credit to scottyearl
