Survey companies can be a way to earn a little extra spending money and test out new products.  I do recommend signing up for coupons, freebies, and survey companies with a dedicated email address (that way you don’t have to sift through them in your personal email).  Here are three legitimate companies:

Toluna gives you the opportunity to participate in online surveys, and vote on and test products, and make your voice heard to the companies, retailers and designers of the products and services you use.  You’ll earn points for cash, gift vouchers and other fantastic prizes while being able to test products before they become available on the market.

You also get 500 points just for joining.

You can sign up with E-Poll to take surveys to earn rewards and be entered into the $1000 Monthly draw.

Sign up with Harris Poll Online to be enrolled to answer questions and influence decision makers in government, corporations and non-profit organizations. You can redeem points for rewards that include a variety of merchandise and gift certificates.
