If you like taking surveys then I’d recommend you give Valued Opinions a try. I’ve been a member of Valued Opinions for over ten years and have cashed out a number of times. They send out quite a few invites and do offer an occasional product test as well. Some of the surveys are a bit long, but they do pay. Right now you will be entered to win a $500 Amazon Gift Card just for registering and activating your account!
