Amazon offers the A Nightmare on Elm Street Collection on Blu-ray for $24.99 (Best Buy has it for the same price via in-store pickup.) Plus, Prime members receive free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping adds $4.98.) That's at least $3 less than you'd pay at a local retail store. It includes all seven films and a large assortment of special features.
