Samplesource.com is offering a number of FREE samples right now. I qualified for Garnier, Colgate, Truvia, Breathe Right and Nature's Path hair and nail vitamin samples. The shipping is free. Just register on their website, take a survey and then pick your samples. They offered samples in April of 2014 as well, so you may already have an account if you signed up last year.
These won't last long so hurry! What samples did you get?
