1. Harris Polls
2. ZoomPanelIf you're looking to earn rewards quickly, ZoomPanel is the survey site to join. They typically send out several survey invitations each week, and have a great collection of rewards to choose from the latest books and movies, electronics, appliances, jewelry, home decor, charitable donations and more.
4. CVS AdvisorOkay, I'm giving up one of my best-kept secrets here, but CVS Advisor is a must-join site. You'll probably only get a few survey invitations a year, but you'll want to respond to those invitations when they come. They reward participants with Extra Care Bucks, and it's not uncommon to receive $10 in ECBs for participating in a single survey.
5. Survey Savvy
If you like instant gratification and cash, Survey Savvy is the site for you. Each survey is assigned a dollar amount based on the length of the survey, and you can request a check for your earnings at any time.
