The third freebie down is for Pinecone Research. Now, I haven't done this in a long time... But back in the day they would pay you $3 - $5 per survey completed. You can transfer this to your PayPal account. They were never really long surveys and you only get a few a month. But hey.. an extra $15 bucks a month was worth it to me at the time and sure did help pay down the credit card bills. =)
It's really hard to find invites or get them from friends for this site because they are so rarely offered. So even if you're only partially interested, sign up today and don't let the opportunity miss you.
