Online Surveys

I have received several emails for surveys from Greenfield Online. The first one tried to take was about entertainment and it paid $5.00, but for some reason i did not qualify for it. The second one i tried to take was over consumer topics, and i did qualify for this one. it took around 30 minutes and kept asking the same questions just flipped around a little bit. Most of the questions were about the current economical problems and how i feel about them in relation to how i purchase new products now. After this one i took another quiz on a related topic that popped up after i completed the first one. this one asked a lot of questions based on my purchasing influence over my family and wanted to know if had to buy top of the line stuff and replace appliances before they break. All of these surveys take more time than the sites estimate them to and they keep asking repetitive questions that get annoying and the ones that offer cash rewards have a narrow target group that i don't think i will get anything from them except for entries into their sweepstakes.
