I know its another possibly 'not in my local store' game at sainsburys post, but someone might get lucky.
Sainsburys Didcot 11:00am 13/01/08; Battlestations: Midway purchased for £5.00. There was a few in the 'Sale' red box near the games section.
Best price i could find from a google search was £12 at game.com
Will put pic of receipt in next post.
