We have a couple of hot freebies over at Amazon. You actually pay $2 for these samples, but then you get a $2 credit to spend on select products in certain categories at a future date, making these effectively free. What a nice deal to try out some new items. Note that these deals are for Prime members, but you can sign up for a free trial of Prime on their site.
