Become a fan of the Surfrider Foundation on Facebook and get a free sample of Emergen-C's blue-flavored vitamin drink powder.
The two brands are partnering together because they both care about clean water. Share your name, email, address, gender and date of birth to get the freebie. You also have to answer three multiple-choice questions about your Emergen-C habits. Kind of a lot of info for one vitamin packet!
Caveats: free samples for U.S. residents only. One sample per address, per household. While supplies last.
Thanks, Money Saving Mom!
