Sorry it's taken me so long to get back to this...
You go to the website links given in the list, and read about their company. If it sounds like something you are interested in-- give them your contact information and fill out the demographic profile. Based on the profile, if you meet the profile they are looking for, they will send you surveys links by email. You do the surveys, and get paid for doing them. Some pay cash, others pay points, that build up and you can cash them in when you reach certain levels for different things. Some companies do a "cash" option, others use Amazon.com gift cards, some use merchandise. Just depends on the company. I have been doing this kind of thing since 1997-- and I really enjoy doing it--and have made quite a bit of extra money by doing the work.
Some companies send nothing. Others send quite a few surveys. It's not a full time job by any means-- just something for extra spending money. The more companies you register with, the greater your chances of getting more to do.
Thanks!
I had thought about doing mystery shopping but I heard that you might not get paid back the money you spend out of your pocket.
I'll check it out!
