Got very lucky !
I really didnt feel like bothering with the midnight launch, so I decided to leave it until this morning and get to Sainsburys for 7am...
However at 6:30 it was too cold and dark, so I decided to stay in bed. I finally got to the "big" Sainsburys at 10:00 and yeap, they were sold out, from 7am !!
So I had to go into town to GameStation for my pre-order
On the way down the escalator I noticed, out of the corner of my eye, a MW2 cut-out in our "little" Sainsburys (in town). I mooched in and they had 4 copies left
