Take a look at the freebie being promoted by PETA. This is live on their site (link posted below). Once on the site, scroll down to the form and fill it out with your mailing info. This freebie, like most others can take up to 8 weeks to arrive at your door so please be patient. All samples are only available while supplies last.
