Not sure if you all know about this site, it's actually pretty new to me also
What you actually do is you sign up and fill in OPTIONAL surveys that help them match you up to the perfect campaign that suits your interests, then the more you spread the word about that campaign the more of a higher score you get and the more campaigns you'll receive!
You're probably thinking "Campaigns?"
Yep, that's what they're called and what it is, is FREE stuff *YAAAAAAAAAAAAAAY!* Everyone loves a good ole freebie.
I just joined a Campaign on feminine care products that i will then be sharing and reviewing with you when i receive them so stay tuned!
