I do a few surveys here and there for extra cash or prizes. My requirement is that the survey has to be fast and easy - I don't have hours to spend on the internet for a minimum return. HCD surveys fit that bill - they tend to be only a few minutes and typically require a short video which is interesting and a different format. The points add up pretty quickly and tend to be around 50 points each. 1000 points is equal to $10. So, if you start now and do a survey or two a week, you should easily have some extra cash by Christmas!
