Amazon UK offers Battlestar Galactica: The Complete Series on Blu-ray for $24.84 (£19.99). At checkout, it drops to $20.70 (£16.66). With $3.83 (£3.08) for shipping, that's $6 below our August mention and the lowest total price we've seen. (It's the best deal now by $15.) It includes all 75 episodes on 20 discs.
Of note, although the episodes themselves will play on U.S. Blu-ray players, the extras and special features may not.
