Amazon.co.uk offers Battlestar Galactica: The Complete Series on Blu-ray for £25 ($39.27). During checkout, it drops to £20.83 ($32.72). With £3.08 ($4.84) for shipping, that's a buck under our May mention, the best price we've seen, and $21 less than what Amazon charges in the U.S. It includes all 75 episodes on 20 discs.
Of note, although the episodes themselves will play on US Blu-ray players, the extras and special features may not.
