Amazon is running a sale on its Blink home security devices. Among the items that have seen a price drop is the Blink Video Doorbell, which is available for a record low of 30. That's half what you might otherwise pay for it. The doorbell allows you to answer your door using your phone. You can see who rang your doorbell via a 1080p video stream (there's an infrared night vision mode) and chat to them using the two-way audio feature.

We are just a few days from the official kickoff of Amazon Prime Day, but the deals have already been filling up our inbox. Amazon's well-reviewed Echo Buds earbuds are on sale for 25, which is half off and a record low price. Amazon's Echo Buds actually made our list of the best budget wireless earbuds, and that was at the full 50 price. We appreciated the lightweight form factor and the pocket-friendly case, both of which contributed to enhanced portability. This is a record low price.

It's no secret that robot vacuums are some of the most expensive gadgets you can get for your home. But Black Friday robot vacuum deals make it a bit easier to grab one, and this year is no different. A handful of machines from Shark and iRobot have dropped to record low prices for Black Friday, including a few of our favorite models. You can snag a Roomba for as low as $159, which is one of the best prices we've seen all year. But before making a purchase, we recommend thinking about the type of home you have and how you'll use the machine: do you have carpet or mostly hard flooring?
