Free pedometer from Nature's Bounty
You must opt into the e-mail list and agree to receive news about promotions and deals to get the freebie, but you should be able to unsubscribe later if you don't like being on the list. You can also get a $2 off vitamin coupon for registering for the free Healthy Rewards program. The sign up form is similar to the one for the freebie.
While you're signing up, check out the site's how healthy are you quiz, which measures wellness. I am a sucker for quizzes and scored "well," though the form suggests I take a multi-vitamin.
Caveats: you must be 18 or older to receive a free pedometer. One pedometer per household.
Thanks, Frugal Freebies!
