I've been using my fitbit with Earndit for sometime. Last night I found out that I can also connect my fitbit with Walgreens and earn some extra points, also FitStudio through Sears. I like earning extra points for what I'm trying to do anyway.
And badges. I like getting extra badges.
Through FitStudio I've earned 825 points which translates into about 82 cents. It's like getting a coupon for just staying active.
