I have just saw some real bargains at my Local Tesco, picked up Miami Vice and Layer Cake at only £2 each. There were others though and I have listed them below:
40 Year Old Virgin
Curse of the Golden Flower
Days Of Thunder
Fly Away Home
Night At The Museum
Sound Of Music
The Big Lebowski
War Of The Worlds
Might be worth checking out your local store to see what they have on offer, I was surprised to see such good titles at only £2. There was a few £1 ones such as a film Called Nugget but its not worth wasting my typing on them.
PS: If anyone sees any others then let me know and i'll just add them to the list. Cheers.
EDIT: Thanks to DarkKnight, edi, jimmy67, whizzkid and Rhys135. I have added the names of your individual deals to the list.
