Back in 2007 I joined a mommy site that I began being asked to perform reviews for their sponsors. At first I got asked to try things like food, and still get food mainly, but then in 2009 I got asked to review the Hoover Platinum Vacuum.
Many reviews included these items over the past years
Yoplait Smoothies, Betty Crocker Potatoes, and recently was asked to try Paper Mate InkJoy 100 Stick Medium Point Advanced Ink Pens, 10 Colored Ink Pens- absolutely LOVE these pens.
I am also a member of BzzAgent, which I have reviewed products such as Cover girl, Claritan, and CarMD
Another company that reviews can be found is at VocalPoint. I have received makeup, cleaning supplies, and juice.
I usually will not only review the products but also host a giveaway of the item. My Memories Software was one I was asked to review and host a giveaway. Now I host a giveaway for My Memories every 4 months along with offer weekly freebies.
