Gawd bless the missus. She managed to blag me a Wii from Woolys in Ilford Essex. Apparently they get a few in everyday (about 6-10 daily) with no pre orders. Worth a shout if anyone lives close by.
I think it would be too late at 3.30. Give them a bell first thing and ask. I reckon they will have some in. If not Game on the ground floor have them in but are keeping them for the pre orders that havent collected.
