BuyDig via eBay offers the Jamsonic Bluetooth Activity Sports Tracker Bracelet in Grey, Black, or Pink for $20.49 with free shipping. That's $3 below our mention from two weeks ago and the lowest total price we've seen. (It's also $15 under the lowest total price we could find for a comparable fitness tracker.) This water-resistant bracelet is compatible with iOS and select Android devices and tracks steps taken, distance travelled, calories burned, active minutes, hours slept, and quality of sleep.
