A year ago I was utilizing around 6 different money making websites. Of those, I am still using 3: Mypoints, Beezag and Swagbucks. I've actually been a member of Mypoints since 1/14/2004 - but that is a discussion for another post. :)
Just by doing my normal searching using the Swagbucks toolbar and remembering to do the daily points about half the time, I have been able to redeem 1 - 2 Amazon gift cards almost every month. I ordered my December one about a week ago, and am close to being able to order another one. (Previously I was much more consistent with the daily points and checking for videos, plus I was doing some offers - so I earned quite a few more cards each month.)
Swagbucks now has several more ways that you can earn points, such as the video rewards (which are similar to Beezag,) and the games.
Using the different reward sites really does not take very much time, and can net you some extra cash which you would not have otherwise. To see previous posts on Beezag or Swagbucks, see my Money Maker topic. As always, if you have any questions, please feel free to ask!
