The Tile App via eBay offers the Tile Mate for $9.99 with free shipping. That's $4 under our Black Friday mention and the best price we've seen for a single Tile Mate in over a year. (It's the best today by $5.) It attaches 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. It has a 150-foot range.
