Paid Surveys

They include sites that seem to be their competitors because they earn referral fees when you buy memberships. A couple mentioned in scam forums even try to dupe you into buying the same list at other membership sites they own under different names. Naturally, these sites also have an incentive to exaggerate how much you'll earn from online paid surveys.
Like American Consumer Opinion, Harris Poll Online offers cash incentives to people who are willing to log in regularly and complete online surveys and questionnaires. Once you join, you’ll begin earning rewards for each survey you take. Once you earn enough reward “points”, you can turn them in for purchases made on websites like Amazon, iTunes, Home Depot and Walmart. Conversely, you can also turn in your points for movies, books, and home goods ordered straight from the Harris Poll website. Plus, you’ll be entered into a $10,000 sweepstakes each time you complete a survey.
After joining a survey site, you provide some personal and demographic information, which legitimate survey sites will keep private. That information will be used in choosing participants to take surveys on certain goods and services. If you get selected to take part in a survey, you will be notified through mail to take a short survey to see if your profile suits that survey. When you are deemed qualified, you will be requested to take a longer survey.
It’s a very well-known scam. You cash the check, then they ask you to either wire some of that money back to them as some sort of fee or buy something for them and send the item to them. So, you deposit the check, then wire some cash to them thinking that the check you just deposited will cover that. A few days later, after you already send them the money, the check will bounce and the money you send to them will come out of your own account.
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.
