By that I mean that once set up you don’t have to promote them, or pay advertising, or incur running costs. One of best has has been as an affiliate for Andy Shaw’s Revolutionary Book  “Money for Nothing Your Property for Free” . I have this linked in one or two places and over the past few months I’ve earned 21 commissions. Other affiliate schemes that I’ve often aggressively pushed have often made no where near so many sales, Internet Marketing seems to be a pretty inexact science. So although by blogging it I am breaking the whole point of this Post I’ve got to say thanks Andy Shaw.
