If you’ve been thinking about signing up for Amazon Prime but balked at the $99/year membership price, check your calendar: if it’s still Nov. 18, that annual subscription will cost just $79.

It’s all part of Amazon’s plan to promote its new original series, The Grand Tour, starring former Top Gear guys. You won’t be required to actually watch the show to get it, but you do have to be a new member and sign up before 11:59 p.m. PT.

The price in your cart will still show $99, but the promotional discount will be applied once you check out. After a year, you’ll have to pay $99 like everyone else.

Along with free two-day shipping, Prime membership comes with access to Prime video, free photo storage for families, an on-demand music-streaming service, a library of free e-books, access to Audible channels, and free audio books.
