I get this question a lot.
Here are few reasons why:

There are HUGE benefits to promoting affiliate programs with your own homebased Internet business. Let's look at 5 of the best reasons to join affiliate programs.

A.No Production Costs: The cost to develop and produce a new product is prohibitive for almost anyone who wants to start a home-based business. With affiliate programs, you have no costs related to the products.

B.Low Set-up Costs:Starting a home-based Internet business is relatively cheap if you compare to a brick and mortar store. Basicaly what you need is a computer.

C.Affiliate programs, on the other hand, are usually free to join, and geographic market reach is limited only by the affiliate's ability to promote his website.

D.Sell Almost Anything:There are thousands and thousands of affiliate programs selling every product under the sun.

E.No Sales Experience Required: Usually the companies you affiliate with will provide training material.
