When almost all revenue sharing websites pay peanuts and some even broken peanuts for your contribution, time and effort you spend on their site, I wonder whether there will really be a website from which we can get free money online. Even if it is true, I think there may be some hidden aspects behind such an offer of free money.
That means, the site may pay you one cent and earn one dollar with your time and effort. In the bargain, who is the winner? You or the site? Anyway, you can try a site called free.com, which boasts "why pay, when you can get it free" below its title. Here, there are many categories for you to choose from.
