Someone posted a great deal for the Xbox/PS2 variant of this deal a few months back (still available), but at that time the Wii pack was a lot more - £60 or more, as I recall. Anyway, it's now come down to £52.25, including delivery to the UK.
It's through amazon.de (Germany), but you just log in with your amazon.uk account and click through the checkouts. It's £69.99 through the amazon.uk site, which is pretty much the next cheapest alternative.
Compatible with the Beatles game, which you can get for £14 on amazon.uk. Decent Christmas combo for £66!
