NFO Reward Points for taking surveys (convert to cash & prizes). In addition to the points you earn for answering surveys there is an Extra chance to win every day you log in to MySurvey.com. If you are not qualified for a survey, you still have a chance to win in a special raffle or in the daily Giveaway It doesn't take much to get your first check (even less if you win the raffle) and they really pay. I already received some checks.
Bottom line:
Frequency of surveys: once in a couple of days
Average pay for survey: $2-5
Remarks: If you are going to sign in only for a few survey companies, make sure that NFO - My survey is one of them.
