Not sure if your the flight simulation types... But I've bought the whole of England and Wales for my FSX for £29.99 (+ I think it was £1.99 postage).
I was going to stick to Scotland but for this price it's worth getting.
It turned up this morning and it's all 3 volumes in as they are normally just wrapped in a box.
Each volume normally is about £25 each.
This is meant to be a email subscriber deal only... but I'm sure they won't mind! :)
Think I might have broken something while trying to post this... :(
