As one of its daily deals, Amazon offers Prime members the Alien Anthology on Blu-ray Disc bundled with Prometheus on Blu-ray Disc for $20.99 with free shipping. (Non-members can spend $35 or more to bag free shipping; otherwise, it adds $3.98.) That's the lowest total price we could find these items sold separately elsewhere by $24, although we saw it for a buck less two weeks ago. The Alien Anthology set includes the original theatrical versions of Alien, Aliens, Alien 3, and Alien Resurrection, as well as the 2003 special editions, documentaries, and other special features. The Prometheus set includes a digital copy plus both Blu-ray and DVD discs. Deal ends today.
