Best Buy is running a pair of sales on 4K Ultra HD Blu-Rays. One of them gets you two select movies for $30, and the other gets you three select movies for $50. To take advantage of the deals, visit the links above, check the "add to offer" boxes next to the movies you want, and click the "Add to Cart" button at the bottom of the page. The discounted prices will appear during checkout.

What kind of movies are we talking? They're mostly blockbusters that are dripping with special effects--the kinds of movies that really shine on a 4K display. In the "two for $30" category, you can choose from films like Alien: Covenant, The Martian, Kingsman: The Secret Service, and X-Men: Apocalypse. If movies based on video games are more your style, you can go for Assassin's Creed and the 2015 version of Hitman.

The "three for $50" offer contains movies that originally retail for higher prices, like Wonder Woman, It, Kong: Skull Island, Mad Max: Fury Road, and Best Picture nominee Dunkirk. For DC comic fans, you can select movies like Batman v Superman: Dawn of Justice, Watchmen, and Suicide Squad. And if you want to explore some gritty classics in 4K, you can go for Blade Runner: The Final Cut or Christopher Nolan's Batman trilogy.

Even if you're not interested in enough movies to take advantage of the offers, each movie is on sale for $20. That gives you a savings of between a $3 and $15, depending on the movie.
