Amazon is offering discounts on two Universal Clasic Monster Collections, but the deals end soon. Universal Classic Monsters: Complete 30-Film Collection (Blu-ray) Universal Classic Monsters: The Essential Collection (4K Blu-ray) If Guillermo del Toro's Frankenstein has you interested in checking out some iconic horror flicks, you'll want to head over to Amazon before the end of the day. The retailer is currently offering a limited-time deal for Universal Classic Monsters: The Complete 30-Film Collection on Blu-ray, which pulls together 30 classic films for $57.49 (was $85). If you prefer 4K Blu-ray, Universal Classic Monsters: The Essential Collection gets you eight icons for $66 (was $91). Both deals are set to end at 11:59 PM PT, so snag them while you can. This bundle gets you an impressive 30 films released between 1931 and 1956. These are spread across eight collections revolving around Dracula, Frankenstein, The Mummy, The Wolf Man, The Invisible Man, Phantom of the Opera, and the Creature from the Black Lagoon. Each one is a complete collection, ensuring you have all the classic films in one place. Aside from the old films on Blu-ray, this bundle is packed with bonus content, including: Better yet, you'll get a 48-page collectible book alongside the Blu-rays, giving you a chance to dive deeper into the films while away from the screen. For something a bit smaller, check out the Hammer Horror 8-Film Collection. On sale for $17 (was $36), it pulls together Brides of Dracula, The Phantom of the Opera, The Curse of the Werewolf, Night Creatures, Paranoiac, The Kiss of the Vampire, Nightmare, and The Evil of Frankenstein into a single collection. This collection offers many of the same bonus features as the Blu-ray bundle, but it only includes eight films: Offered in 4K Blu-ray and benefiting from support for Dolby Audio, this is arguably the best way to enjoy these old movies on modern screens. Another bundle, Universal Classic Monsters: Icons of Horror Collection, is also on sale for $35 (was $43). It's a bit smaller than the above 4K collection, featuring just Dracula, Frankenstein, The Invisible Man, and The Wolf Man. But at this new low price, it's worth consideration if you don't mind missing out on a few hits.
