I have not had good luck either with the survey's. I rarely qualify and on the rare occassions I have I did not get credit. On Quick Rewards I do the trivia and the clicks and some shopping. On Sunshine rewards I do the Daily stuff, and some shopping. It is the shopping that really adds up, but that is assuming you do alot of shopping via the internet. I will occassionally do sign ups at both sites but it has to be something you have never done before (ie. if you had netflix a year ago you won't get credit and you can't do the offer cancel and then do it again a month later.
I also do 2 other ones Reward TV which you get points for answering questions about TV shows and commercials, and Moola.com where you play games like Rock Paper, Scissors, Hi/Lo, and a Gold Rush game. They give you the first penny then it is set up sort of like Who Wants to be a Millionaire. You bet .02 to win .04, bet .04 to win .08 , etc. If you want more information PM me.
