How to Cash In on Your Opinions -- Savings Experiment

If you're looking to make extra cash, your opinions could earn you as much as $100 an hour. Here's how to make money by giving companies a piece of your mind.

Market research companies use focus groups to gather information about a product. You may be asked about your perceptions, beliefs, likes, dislikes and more. Your opinions offer valuable data, which is why companies are willing to pay cash for them.

If you can't participate in person, there are online sites like iSay.com that reward users for their opinions with points, charities, gift cards or cash. Mysurvey.com is another site that allows you to earn rewards for taking online surveys and testing products.

Don't just sign up for any market research site, though. There are plenty of scam sites out there posing as the real deal so that they can collect marketing information on consumers. Use resources like SurveyPolice.com to read reviews and assess the validity of any questionable site.

So, if you have a bit of extra time and want to pocket some rainy-day money, let your opinions work for you. The rewards can add up quickly.
