If you create your own informational products, your profit margins are extremely high as opposed to buying and re-selling someone else’s product, or service.
 
When buying someone else’s product for re-sell, you receive a discount, or wholesale price that you sell at a marked up retail price point. Your profit margins are dependant on the product, and several sales transactions must occur to make any significant income.

By creating your own informational product that is based upon your own subject matter expertise or experience, you eliminate your wholesale cost. Secondly, the costs associated with creating informational products are very minimal.

There is a huge market for informational products, because market place is constantly evolving and people need information to manage to these ongoing changes.
