As one of its daily deals, Best Buy offers the Jawbone UP24 Sleep/Activity Monitor Wristband in Small, Medium, or Large in Persimmon for $69.99 with free shipping. (Select "Red" to see this price.) That's tied with our mention from two weeks ago as the lowest total shipped price we've seen and a current low by $15. (We saw it for $20 less in-store at Walmart two weeks ago, but stock was limited by ZIP.) It tracks your sleep patterns, steps taken, and calories burned, and allows you to log the food you eat. It connects via Bluetooth 4.0 to phones running Android 4.3 or later or iOS 6.0 or later. Deal ends today.
Note: It's not guaranteed for delivery by Christmas.
