The Matrix - blu. been waiting ages for this to drop in price. looks like it never will so i thought fuck it, stop being a tight bastard, lol.
Casino Royale - blu. this was pretty cheap (£3) when you consider that the disc is held up by some as reference quality.
Shaft - dvd. the 1971 original with richard roundtree. £0.50 and still wrapped in its plastic cover
i'm positive i've already got it though
