The real sale will probably be explosive when it finally starts, but there are still some good deals live now.

While Amazon’s official Black Friday event will start on 21 November, the online giant has been releasing early deals, giving shoppers plenty of time to grab a bargain or two before the annual sale comes to a close on 2 December.

Amazon's early Black Friday sale has the top-rated Blink Video Doorbell on sale for its lowest price ever. The Blink doorbell alerts you when motion is detected and features infrared night video, two-way audio, and a long-lasting battery life.
