Amazon have started their January sales on DVD and Blu-ray
Many titles on there. I did a quick search of the DVDs, and I couldn't find (the handful that I checked) them cheaper.
Twilight (1 disk) £4.98; (2 disk) £6.88
Confessions of a Shopaholic £4.48
Xmen - Wolverine £6.98
Marley and Me £4.98
I also don't own a player for Blu-ray so have no idea if these prices are good (sorry!)
Matrix triology £16.98
The Ultimate Bourne collection £17.88
apologies if this has been listed already, I have done a search and couldn't find anything.
