Sell on Amazon
Amazon, among other websites, is a powerhouse seller for self-published authors to use to sell their books. Some people will only ever go to Amazon to buy a book, and you, as an author, need to know how to get your books on Amazon to market to those potential customers.
Amazon has stream-lined the process of selling items through their website into a simple, yet easy to use two tiered format. They have two categories of sellers, one for the person(s) who sell more than 40 books, and ones who do not.
