Possibly a bit left field but I'm in France just now and FNAC have a nice deal of special editions -
1 blu-ray collector = 20
Not sure what the shipping would be to Britain although I have ordered from them before. Picked up Exorcist, Black Swan and Blade Runner. Really nice digibook editions mostly exclusive to FNAC. Fair enough, the text is French but there are some fabulous glossy production stills in the digi book blurb.
If you like something a bit different.....
Oh, and I'm deffo buying Jaws out here as well. A touch cheaper than home and the French title is beyond genius - Teeth of the Sea
