ASDA had Fifa 08 for PS3 in store today for £25.00. Didn't appear to be on "sale", just appears to be a new price for it. Cheapest I've seen it new by far (including online).
Thanks to DelBoySmiffy, for letting me know NFS Pro Street is available at the same price in store.
The ASDA store was "The Jewel" in Edinburgh, not been able to check other ones.
*edit* First post, btw :)
