I love easy to start businesses and they don't get much easier than this. TonerBuyer.com has a cool program where you hand out pre-paid mailers to anyone who uses printer cartridges (businesses in particular) and when they mail them in, you get paid! You then go around and pay the businesses and everyone wins. Since these companies are used to getting nothing for their old cartridges, they will be more than happy to help you out - this is free money!

To get started, just go to TonerBuyer.com and fill out the application. Once you are approved, they'll send you a free starter kit. I don't know how many businesses you can start for nothing and potentially end up making a few grand a month, maybe more, but there aren't too many of them.

So there you have it, now you know how to start the world's easiest business.
