I work for a marketing research company and we are regularly involved with surveys that pay between $2 and $10 depending on how long they take. For a $10 survey, be prepared to sit at your computer for at least half an hour. Survey Spot is a company that we are associated with that will pay for you to take a survey.

Also, there are various filters in place to make sure that you aren't just rushing through the survey to make the money. You won't be notified about new surveys if you enter bad data.
