1. The Amazon Store.The first and most obvious place to get free books for your Kindle is in the Amazon Store itself. What you need to do is go to Amazon’s page for Kindle books. Next, navigate to whichever type of book you are looking for-there is a genre list on the left side. After clicking on whatever genre interests you, in a box on the right side of the screen, sort from lowest price to highest price. What you will have is a list of all of the books in the Amazon Store from the genre you selected, starting with the free books. After you have sorted from lowest price to highest price, you can navigate from one genre to another, and the list will automatically be sorted by price.
