As a reader discovered, Amazon offers its second-generation Amazon Echo Dot in Black bundled with the Tile Mate with Replaceable Battery 4-Pack for $59.99 with free shipping. That's $20 under the lowest price we could find for these items purchased separately elsewhere, although we saw this bundle with a third-generation Echo Dot for the same price last month.

The Echo Dot features Alexa voice control, 802.11n wireless, Bluetooth, and a 3.5mm audio output. The Tiles attach to something that you don't want to lose, such as keys or a backpack, and can be tracked by Tile's mobile apps, as well as Alexa.
