The price of a one-year subscription to Amazon Prime has been slashed by £20 to just £59. The deal started yesterday, and is available until Wednesday.
As well as free one-day delivery on thousands of items, a subscription to Amazon Prime gets you Amazon Prime Instant Video, Amazon's streaming service.
The service offers thousands of films and TV shows, as well as a host of original content, such as 'The Man in the High Castle'. It's also the exclusive UK home of 'Mr. Robot'.
Amazon is using the deal to promote Black Friday, a huge discount shopping day in the run-up to Christmas. This year it takes place on Friday November 27th. It started in the US, but has become increasingly popular in the UK over the last few years.
Under the new deal, Prime costs just £4.92 a month, which is less than the cheapest Netflix subscription.
Last week, Prime Instant Video came to the Roku Channel Store, meaning owners of Roku-made set-top boxes can stream films and TV shows through Amazon's service.
According to Ed Lee, video president of content acquisition at Roku, this gives the platform the best line-up of services available.
"Amazon Video is one of the most popular streaming services among British consumers and we are delighted to make it available to our UK customers," he said.
"With the addition of Amazon Video in the UK we now have the most comprehensive streaming channel line-up among major video streaming services and catch-up TV channels."
