It came in the mail today. I finally got selected to fill out a Nielson consumer survey! This is a sweet deal that I have been hoping to get ahold of for some time. Fundamentally, I get $10 if I fill out a paper survey and send it back in the included prepaid envelope! What a dream come true! They even sent a $1 bill in the letter as an incentive.
That is what I call an irrefutable freemium offer!
