From now until November 19, you can sign up for a year of NBC’s Peacock Premium streaming service for just $20 (normally $50/year or $5/month).

Peacock Premium is the cheapest of the service’s paid tiers , but you don’t miss out on too much compared to the more expensive Premium Plus ($10/month or $100/year). The biggest difference is that Peacock Premium is ad-supported, so you’ll have pre-roll ads before movies and commercial breaks during TV episodes. You also can’t download content to watch offline like you can with Premium Plus.

Otherwise, both subscription plans offer access to all Peacock content, including exclusive movies like the recently-released Halloween Ends, new TV shows like Chucky, and beloved series like Parks and Rec and The Office–which are now exclusive to NBC’s streaming platform in the US. Along with the on-demand content, there are also over 50 always-on channels and live NBC sports coverage to watch, too.

If you want to try Peakcock first, you can sign up for a free trial and check out its library of content. Just make sure you sign up for Peacock Premium before November 19 if you want the discounted price.
