I just signed up for a site called Swaggable where you get freebies to try in various categories, such as beauty, snacks, cleaning products, and even dog supplies.
I signed up three weeks ago and I've already received two samples. One was dried fruit and the other was an eye cream. All you do is add products that you want to your wishlist, and then they will notify you if you are chosen to receive that sample. I love it so far!
