Not the most obvious place to go DVD shopping, but mine has about 3 stands of DVD's, all half price. I got 'knocked up' for £1.49 and XXX for 99p. They had 'mamma mia' for about £6, and loads of kid ones in the carry packs for about £1.50 each, I noticed Bagpuss, Postman Pat and Barbie in Swan Lake, amongst others.
Lots of variety, might be worth having a look if your local one has the same offer.
And please.....no comments about the 'knocked up' lol
