There are a lot of streaming services out there. Some might say there are too many. Looking for a provider that offers as much bang for the buck as possible? Then check out Curiosity Stream, where a Standard Plan lifetime subscription is on sale for $169.97 until January 21 at 11:59 pm PT.

Curiosity Stream works just like any other streaming service. As opposed to offering the same dull selection of movies and shows, however, it instead carries a huge catalog of enriching documentaries to satisfy your thirst for knowledge. And since it costs way less than what you’d pay for Netflix or Hulu, it’s certainly more cost-effective.

Curiosity Stream’s catalog features thousands of titles from top-producing filmmakers, much of what they offer is available in HD, and you can stream using a wide array of devices. And it’s won awards too, including an Emmy for Stephen Hawking’s Favorite Places.

Until 11:59 pm PT on January 21, get a lifetime subscription to the Curiosity Stream Standard Plan for just $169.97 (reg. $399.99) — a savings of $230 off the regular price — no coupon codes required.
