They have loads of decent DVDs in the Asda Living Stores. Im not posting this for Asda Food shops because i cant confirm they are running the same offer.
I was in the Oldham branch and there where loads on offer for £2 Including....
Forrest Gump - Bee Movie - Anger Management - Mr Deeds - Nanny Mcphee - Superbad - Italian Job (2003 version), Shawshank Redemption
Anyway if theres one near you go have a gander there where quite alot.
