Amazon UK offers The Bourne Collection on Blu-ray Disc for $10.02 (£7.99). During checkout, it falls to $8.35 (£6.66). With $3.86 (£3.08) for shipping, that's $4 under last October's mention and the lowest price we've seen. (It's the best deal today by $4.) This 4-disc set includes The Bourne Identity, The Bourne Supremacy, The Bourne Ultimatum, and The Bourne Legacy.
This Blu-ray set is region-free and the films themselves will play on US Blu-ray players, but note that the extras and special features may not. It's expected to ship in one to three weeks.
