ASDA Entertainment are running a 3 for 2 offer on over 100 Blu-Ray DVD's. Unlike most other places, the disc prices are set at £17.97 each (rather than rrp) so you get 3 films for £35.94 - less than £12 each. (£11.98 to be exact).
I just ordered 300, Unforgiven and Pirates. There are many other great titles available also - and most are actually in stock.
Here's a few from the List
Harry Potter - Various
Pirates Of The Caribbean - first two
