It's Black Friday! And that means the streaming deals available right now are almost as big as the hairstyles were in the '80s. Speaking of which, if you want retro sci-fi, you need these limited-time offers in your life to save some cash.

Sure, Netflix is one of the biggest names in streaming, but outside of Stranger Things, it's not a major player on the sci-fi scene, and it's not on offer. If you want the best streaming services and, in particular, the best value streaming services, we've rounded up the top Black Friday offers below.

Here at Space.com, we're big on sci-fi and we're covering Black Friday deals for sci-fi fans, too. Whether it's Tron, Star Wars, Terminator, The Running Man and Ghostbusters on Disney and Hulu, Severance and Flash Gordon on Apple TV, Star Trek on Paramount Plus, and if you want kids riding around on bikes and defeating evil, the IT movies and TV show is streaming on HBO Max.

These deals all end in early December, so you'll have to be quick, but that's still enough time to satisfy your sci-fi needs before the rest of Stranger Things season five is ready to stream.

Okay, okay, if you simply have to watch Stranger Things, we won't hold it against you. You'll only find it on Netflix as it's a Netflix original and it's their biggest show, both in terms of original content and in the sci-fi genre. Here's how to get it, even if it's not on offer.
