I don't know about making a lot, but I do answer surveys for one place that gives 5 to 20 points, sometimes up to 100 or so for extended surveys, or even more for at-home surveys, such as keeping up with a product you agree to try (that they send you). It takes quite a few months, but eventually I have enough points for them to send me 20 bucks. Another one is just clicking on opportunities that are sent to your email. It only takes a few seconds, and you get 5 or 10 points, more if you respond to the offer. After a while, I can trade in points for gift cards to stores, etc.... Those are worth it to me, because they don't take too long. Others I've tried are too tedious or take too long.
