Synovate Global Opinion Panel

Synovate Global Opinion Panel is a mouthful, I know, but this site is worth your attention. Sign up for free and they will email you survey invitations.  By taking these surveys, you get to influence and learn about new products before they come out. Sometimes, they will even mail you a product (think shampoo, air fresheners, cleaners, detergent, food, etc) for you to evaluate. You get paid through points which you can redeem for cash (I've earned $125 and many free products over the years).  By completing surveys, you're also entered into sweepstakes for cash, gift cards and video game systems.
