Amazon's Gold Box contains a special deal for Batman fans today: a bundle of Batman: Arkham Knight and all three Dark Knight movies.

Arkham Knight regularly costs $49.99 at Amazon but is currently on sale for $37.98; it will be discounted to $25 during Black Friday promotions at a number of retailers.

However, those deals won't include the Ultimate Collector's Edition of The Dark Knight trilogy. The six-disc box set includes Blu-ray copies of all three Batman films directed by Christopher Nolan: Batman Begins (2005), The Dark Knight (2008) and The Dark Knight Rises (2012). It also comes with a 48-page book featuring photos from the trilogy, a letter from Nolan and one vehicle from each movie: the Tumbler, Bat-Pod and Bat.

The Dark Knight Blu-ray package regularly costs $59.96, but in today's Gold Box deal, customers can get the movies and Arkham Knight together for $61.98 — a savings of 44 percent. The deal is valid only for the PlayStation 4 and Xbox One versions of the game.
