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.
Toluna – Been a member for maybe 7 years. They probably send 5-10 emails every day! I usually pick and choose 1-2 only because of decent rewards. For them, 3000 points is $1 so you have to be smart about they surveys. Getting 1,500 points for 20 mins seems ok until you realize it’s only 67 cents! Payout is $20 checks that come 1-2 weeks after you request them. It also takes weeks to get credited for a 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.
