I love hunting for freebies. It's so fun getting samples in the mail! Here's a few I've tried I've posted some link's below of some of the best sites that offer great freebies. These are all 100% free to join.

Swagbucks.com is one of my favorites they give you points for searching the web, With the points that you earn you can get Gift Cards, Shirts, Hats, and so much more. It's east to earn points - Swagbucks will also give out free points as well. www.swagbucks.com/horsecrazy16

Smiley360 Is another great site to test FREE products! I've gotten some nice stuff from them.

Hunt4freebies is my top favorite. They update it several times through out the day so you might want to check it often.

Vocal Point Vocalpoint offers fantastic samples throughout the year!

Buzzagent is awesome! They send you a full size products for feedback on what you thought about it. They occasionally give you perks for just being a member. 
What I've received so far:
