Are they any legimate Work at Home Jobs out there?

I have looked and looked for a work at home job to supplement my income because currently I am the only one in my household left with a job and my paycheck is not stretching far enough. The other members in my household have not been able to find any kind of work. I have checked out so many websites and they all just seem to be scams which is a waste of my time. Frankly I am tired of wasting my time. I do not want to start my own business. Is there anything out there that is truly legimiate that is worth a look?
