The Fitbit Flex drops from $99.99 to $59.99 and comes with a free three-month trial of the FitStar Personal Training app at Kohls.com. Shipping will add $8.95, but you can choose in-store pickup to avoid the extra cost. However, even with shipping added, this is still the best deal we could find for the Flex by $3. The included FitStar Personal Trainer app is optional and the free premium membership trial will cost $7.99/mo after the trial period, but even if you opt out, the app still offers a number of free features that can sync with the Flex's step, distance, calorie, and sleep tracking features. A large and small band are included and sales tax is charged in most states.
