Market research companies can pay you in different ways. Incentives depend on the company and on how much time and effort is spent participating in the focus group or survey. People always try to find ways to get involved in it. Recently, I've found a website that is FREE and COLLECTED ALL INFO YOU NEED.
FROM THIS WEBSITE WWW.GAINOPTION.COM
I found lots of lists of PAID THINGS,like PAID SURVEY, PAID READING EMAIL, PAID TO DRIVE YOUR CAR, PAID TO SHOP AND EAT, PAID TO WATCH TV, PAID TO TAKE PHOTO, PAID TO BLOG, PAID TO SELL ON EBAY. These surveys OR other things do work and they do pay you.
