I got in on the Bzzagent Neutrogena campaign! At first they said they were full when I first tried, but then I tried again, so if you want in and didn't get in, check in a few days to see if there are any openings!
I have been wanting to try some new makeup but I am trying to not spend money on that sort of thing right now
If you don't know what Bzzagent is, you can read about it here - they have you try products and tell people about them, when you report your results you get rewarded in MyPoints, which is redeemable for lots of good gift certificates. (like free Target, Walmart, Starbucks, Marriott, Olive Garden, Red Lobster, Burger King, Macy's, Panera Bread, Amazon gift cards, etc)
