I also have used Synovate Global Opinion Panels, which is now I-Say by Ipsos. They send you surveys pretty frequently and the points you accumulate can turn into actual money! You can receive an actual check from them, or choose to redeem for a gift card. I haven’t cashed out with them since they changed into the new system, just because I’ve really stopped taking the surveys because I’m lazy 🙂 Here’s the link: http://i-say.com/Rewards/RewardsProgram/tabid/203/language/en-US/Default.aspx
One of the most popular sites, and rightfully so, Swagbucks offers traditional surveys as well as a range of additional ways to make cash. Filling out surveys for money will reward you with points called Swagbucks which can be cashed out through PayPal, or redeemed as gift cards for shops including Amazon.com. As a sweetener, they’ll even give you $5 just for signing up.
You won't get rich doing these things but it's legitimate and you'll get paid in the end. For example, you get a penny for each email you click. You get a penny for a video stream. You can earn dollars for fulfilling offers but those aren't nearly as quick as reading an email. They are upfront in what you get paid so you can decide if it's worth it.
Taking paid surveys can become a well paying job if you work hard enough at it but you won’t start bring in buckets of money right from the start. But don’t let that demotivate you to start taking paid surveys. In the beginning you don’t have control over the survey offers you receive, but if you keep at it then after some time your per-survey-rate will go up as you become a more reliable source for paid survey companies. Then you’ll be surprised how much extra money you can make without putting in very much effort at all.
IOCS is a not-for-profit research organization that conducts studies and experiments on shopping-related behavior – things like how we, as consumers, evaluate products, how we make the buying decisions, etc. Although the focus is mostly on shopping related behavior, some of their experiments and studies include broader areas of marketing, psychology, and economics.
