Smile.ly is a program which gives you opportunities to try new products and share about them with others. Sign up here and complete your profile and then check your "My Profile" page to see if you have any offers.
I just signed up (it's free and took me less than 3 minutes to do so) and immediately received an offer to try a full-size bottle of VitaCraves. Many others are also receiving this same offer when they sign up right now. So if you have a few minutes and like to try products for free, it's definitely worth signing up for!
