For all you maths fans, that brings the fitness tracker down to $90 ($89.95, to be exact), which is a fantastic deal for one of its latest and greatest fitness trackers and one that won our Wearable of the Year and Fitness Tracker of the Year awards at the Wareable Tech Awards. To put things into perspective, you'd normally be parting with $150 for it.
Fitbit Alta HR - $89.95, save $60 - Amazon
Fitbit Alta Special Edition - $119.95, save $30 - Fitbit
It's also less than what Fitbit is asking for at its own shop front, where it's currently $119.95, although that offer will run all the way until 21 July. On Amazon, you've got just a day and a half (even less, when you're reading this).
The Fitbit Alta HR is one of the best fitness trackers money can buy right now. While less substantial than the Versa or Ionic (both Fitbit's smartwatches) it's a great all-rounder that tracks heart rate, sleep, and packs a 7-day battery life. It also looks pretty good.
Sadly Fitbit tells us the Versa won't be getting a deduction (it's still pretty new, remember) but here's a selection more deals now live from both Fitbit and Amazon.
