Amazon.co.uk offers Star Wars: The Complete Saga on Blu-ray Disc for $62.61 (£40). That falls to $52.17 (£33.33) at checkout. With $4.82 (£3.08) for shipping, that's tied with last week's mention and the lowest total price we could find now by $19. This 9-disc set includes all six feature-length movies and more than 30 hours of special features.
Note that although Amazon.co.uk lists this as a Region B/2 set, multiple Blu-ray review sites state that it's region-free and will work with Blu-ray players worldwide.
