The most profitable mail order products are simple 3-to-5 page informational reports such as this one.  Once you've got your act together, these 3-page reports can be produced for $10 per hundred or less, and sold for at least $200 per hundred.

Generally speaking, everybody either in or wanting to get into mail order, feels that they have the final answer to what the general public will beat a path to their door to buy.  The problem is that once they've invested a good deal of hard-earned cash and countless hours, their programs don't sell quite as well as they had hoped they would.  Thus it is that these people begin to feel that they've left something out or perhaps not doing "some little thing" that they should be doing.
