Get paid for doing online surveys?

I do surveys for several sites. I have gotten paid from some of them. You can't earn a living from them, same as with mylot. I get checks for $5 sometimes. Some of the surveys give you points, you save up your points for money or gift cards. Sometimes you get products to test out and then give your opinion on. I got lucky with one site, It was about snacks. They sent my a palm pilot to record my snacking for 2 weeks, they sent me a $10 bill. After I send the palm pilot with my data on it, they will send me a check for $60, I haven't recieved the check yet, but I will. Also you get sweepstake entries, for doing surveys.
