What are some good ways to make money online?

I am looking for a legitimate way to make money online. I really want to be able to make money from home to help me with the state of the economy. Please let me know of any legitimate way to make money online without having to pay. I'm not even looking for something that is a scam, since it seems to be all I can find online these days. Please let me know of some websites that some of you have tested and are known to work without problems. Thanks in advance and your help would be greatly appreciated.
