Just received a newsletter email from Blockbuster and it mentioned they had Blu-Rays for £10 or less online or I think they are 2 for £20 in-store.
I had a look and there were a lot of good ones, well imo anyway. sure some will be cheaper elsewhere but defo worth a look.
The cheapest title I have seen so far of Saw IV at £6.94
It is also Free P&P
