Last year, Best Buy offered an exclusive A Nightmare on Elm Street Blu-ray collection that contained all seven original films. There were very limited quantities and sold out quickly, but it has been revealed that Warner Bros. is preparing a full North American release.
The collection will be available everywhere on March 5th with a retail price of $59.99. However, if you're looking to pick it up early, it appears that Amazon.com does have some stock already for sale. They are selling the set for $49.95 and currently have 19 left in stock: http://www.amazon.com/Nightmare-Street-Collection-5-Disc-Blu-Ray/dp/B009NH9IMM/
