Transformers movies might not be Oscar-contenders, but when it comes to summer blockbusters and watching millions of dollars of pixel clobber each other, this series is hard to beat. If you’re a fan of the franchise, you can grab the limited-edition steelbook collection of six high-octane action movies for only $85 at Amazon right now. This collection released last year with a retail price of $135, so this is quite the offer. As with most Amazon deals, there’s no telling when this offer will disappear.

The only downside is that it doesn’t come with last year’s entry in the franchise, Rise of the Beasts. But if you want to complete your Transformers steelbook collection, you can snag Rise of the Beasts for $38–which admittedly sounds very pricey in comparison to the collection. It is worth noting that the $85 price for the six-movie collection is the lowest since Black Friday, when it was on sale for $80. Since then, the collection has remained around $110.

This Transformers collection bundles six films–Transformers, Revenge of the Fallen, Dark of the Moon, Age of Extinction, The Last Knight, and Bumblebee–together into one gigantic collection. Each film is housed inside a unique steelbook, and each case has artwork of key players in the saga, like Optimus Prime, Bumblebee, and Megatron.

As you’d expect, there’s more than meets the eye with these films. On the surface, you’re getting both 4K UHD and 1080p Blu-ray copies of each film, as well as plenty of behind-the-scenes extras that reveal how each movie was made. The total runtime of all six movies is over 14 hours, which equals a lot of explosions from Michael Bay, the master of Bayhem. As an added bonus, each film is also available to watch online, as digital codes for the movies are included.
