Are there any good ways to make extra money online with little effort?

I always see the ads to answer surveys and open emails for money and then when you subsribe to it the surveys are for you to be entered into a sweepstakes or something. I am just looking for a way to make some extra money with putting a lot of time into it since I already work from 6:30 am to 6:00 pm.
