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.
Not a “scam” in the sense of the word, but really not a way to earn any type of money. If you can find the companies that do the surveys and do them on your own with out sites like this you will make a substantially bigger amount of money. The “scam” is they take 90% (if not more, to be honest probably 99%) of the survey payout for themselves. Its the same for the “offers”, they will take the majority of the offer from the company, and give you a small percentage, And if that was not enough, they also take a percentage of your payout. This should be illegal as it is criminal to do this to people.
