A few paid survey sites do pay relatively well in cash. However, many sites hype hypothetical, best-case scenarios that can't possibly apply to each and every consumer for each and every hour of participation. In the real world, the likelihood that you'll often earn the higher of the hyped amounts is slim. Most online paid surveys simply don't pay much, and you must be invited to complete them. To be invited, you must fit targeted demographics. That alone limits your earnings right off the bat, as you can't possibly fit every demographic.
Just like the other survey sites, every time you complete one of the surveys, you’ll receive anywhere from 35-250 points, which equals about $1.50 to $1.75 per a survey. Once you rack up enough cash to payout (which you’ll have to accumulate at least $50), you’ll have several different options to receive your money. You can get your money through a check, through your PayPal account, or redeem it for gift cards.
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.
