Update: Today is the day! If you are looking to pick up a discounted year of Amazon Prime, this is your chance. Don't wait, this offer is only good for one day, November 18.

To celebrate the launch of The Grand Tour, Amazon is making it cheaper to get in on a year's Prime membership in the U.S., and enjoy the new show from day one. On November 18, you'll be able to save $20 on a year of Amazon Prime, with the price dropping to $79 for a day only.

That gets you access to the antics of Clarkson, May and Hammond, but also instant streaming through Amazon Video, photo storage, faster shipping on Amazon orders, and a discounted price on Amazon Music Unlimited.

In related news, the Grand Tour trio have announced that from December the show will be launching globally, allowing viewers in more than 200 countries to catch up on previous shows, and see new ones every Friday.

Amazon UK has been running a similar weeklong promotion for Prime, making the service available for £59, down from the usual £79.
