A great place to do this is Smiley360. It is completely free to join. You get to receive items to review and share the opinions you gather with friends in person and with social media.

I also recommend BzzAgent and can send you an email invite if you comment with your email address.
Really great products come through these companies and they value your opinion! Most kits include several coupons to share as well, so the savings go beyond the initial trial!
