Amazon doesn't often discount its $99 Prime membership fee, but to celebrate the launch of The Grand Tour, a Prime exclusive, the Seattle-based giant has decided to slash that $99 price tag by $20 to $79 for today only.

In case you somehow haven't already heard of The Grand Tour, it's a brand new motoring show with a massive budget that is hosted by an ape (Jennifer Clarkson), a hamster (Richard Hammond), and a long-haired man whom the Italians refer to as "Mr Slowly" (James May). The first episode premiered last night, and it had everything from dead celebrities to communist cars. Reviews were mostly positive.

Until today (November 18th) at 11:59 PM PT, new members will be able to purchase a year of Prime for $79. This will not only grant access to The Grand Tour, but also to unlimited two-day shipping on millions of items, thousands of TV shows and movies, millions of ad-free songs, and loads of eBooks.

To take advantage of this offer, simply hit the first source link below, add Prime to your cart, and check out. The price will still appear as $99 in your cart, but it'll change to $79 at checkout. Unfortunately, the discount doesn't apply to the gift of Prime.
