Amazon offers Prime members the Terminator Anthology Collector's Edition on Blu-ray for $19.99 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping adds $4.98.) That's the lowest total price we could find by $4, although it was $4 less in July. It includes The Terminator, Terminator 2: Judgment Day, Terminator 3: Rise Of The Machines, and Terminator Salvation with featurettes and video archives.
