Affiliate Marketing

Almost certainly this is the only internet business that you can run without owning your own website. However, most major internet marketers have a few websites and many have several hundred.

Websites are not expensive to own these days and they need not be expensive to set up, in fact if you are slightly computer literate you can do it for less than $10.

Invest some time and money learning the basics, and you can use the knowledge  for the rest of your life.
