Tesco have reduced a lot of bluray prices and also have 15% off with the code EX-15OFF15
I found 10 I wanted. good for my bluray collection, not so good for the wallet
among my purchases were the italian job, shooter, a couple of the star trek movies, galaxy quest, the untouchables, deep impact. All for £5.07 each with the discount. you can get another 8% off via quidco which makes them £4.66 each. a bargain basically.
this link should give you a list in roughly ascending price order
