You can pick up extra cash in your spare time by participating in focus groups run by companies that do market research.
“[It's] a great way to earn cash for sitting in a room with strangers and sharing your opinion on something, ” said Jim Wang, creator of the personal finance blog, Wallet Hacks. He signed up with a local marketing company he found through GreenBook. org and was paid $100 for 90 minutes of his time.
You can also sign up through FocusGroup. com to participate in groups. Be aware that you might only be invited to participate in a couple of focus groups per year with any company, so consider signing up with several if you want to earn more.
