My textbook inventory is sold on Amazon.com on Half.com and to other textbook companies. You will not have to advertise your inventory. You will simply have to list the ISBN (International Standard Book Number) of your book on Amazon.com or Half.com. These websites allow you to
list your books for sale on their sites along with other sellers of the same ISBN. Whenever someone eventually sells their textbook on Amazon.com or Half.com the website will take a small percentage of the sales price of the book for themselves. This is considered payment for allowing you to sell on their site.
