I've been a member of Klout for a year and still learning but I've gotten quite a few of free stuff. Klout gives you FULL SIZE products. I've received Roc Stress Relief cream, Jason's shampoo, Lipton tea and honey, The adventures of Tin Tin dvd along with a coupon for free Purina Dog chow and more.

How you get the free stuff is you add topics and have people give you Klout K's so you can get the free stuff. I'm in a group called Klout K's https://www.facebook.com/groups/100124303460991/
where you can post your link to your topics and people can give you klout ks and in return you do the same. Ever since I've joined that group I've been getting quite more free stuff. Today I received a perk for free Essie Nail polish.
