Lightspeed is another reward program that I do. You earn points for taking surveys. Most surveys get you 75 or 150 points and you only need 550 to get a $5 Amazon Gift Code.
You have to qualify for the survey and finish it in order to get the points. I usually qualify for about 50% of all the surveys they send me and they usually add a new survey every few days. Its easy to complete the surveys and most of them take less than 30 minutes to complete.
