I have found an answer. I stopped buying disks a few months ago as I was watching so many films that I have never had time to go back and re-watch the ones I had. Instead I now rent from Tesco DVD rentals, which includes BD aswell as DVD disks. Even their basic plan means that each rental costs just over £1 per film (assuming you do watch 2 films a week). So if the film is naff, it's no big deal.
I do the same from Blockbuster. If they're at the top of the list I normally get them straight away.
Cheap viewing. Love it.
