The Fitbit ONE Wireless Activity and Sleep Tracker drops from $99 to $81.75 with free shipping when you get it along with 2 accessories priced $5 or less at AT&T. This is lowest price we could find for these clip-on trackers by $17. To get the discount, add the Fitbit to your cart and on the following screen where you're asked to add any additional accessories, sort by "lowest price" and add any two $5 items to take an extra 25% off each item in your cart. The ONE syncs with your computer or smartphone with an accompanying app (or natively with the HTC one M8 and other phones) and monitors your sleep, steps, distance, calories burned and stairs climbed. Sales tax is charged in most states.
