Currys Digital have a big poster advertising the Xbox 360 Elite for £159. I didn`t get a chance to go in store to check the details, but, judging from the poster, it looks like the deal should be nationwide.
I`ll try to go in tomorrow to double check.
Edit - It was the Dundee store I saw the poster in, but the poster was a proper printed one, not a `Manager`s Special` flipboard.
Edit2 - Price edited from £150 to £159.
