I have just bought a Sony PSP 3000 with FIFA 09 for £127.20 in Sainsburys.
The next cheapest that i've seen is £129.99 with a free game, one of the cheap games, at Argos. The one in Argos is one of the coloured ones but I wanted one of the black ones and for that they charge £149.
The price on the shelf was £129.99 but they took the VAT off at the til so it ended up at £127.20.
I can't see this online so I guess it's just instore.
I hope this helps.
