Anyone looking to read Kindle books on the cheap has a number of excellent options. The following sources can provide tons of reading material for all age groups and almost every taste.
Many Amazon Kindle books can be loaned one time for a two-week period. BookLending.com matches people who own lendable Kindle books to others who want to read them. You can easily sign up for the free service and enter the books you're willing to lend along with the ones you'd like to borrow from others. You'll receive an email anytime someone offers to loan you a book you requested or when someone requests one of your available books.
Drawbacks to the BookLending.com service include the fair number of Kindle books that can't be loaned as well as a potentially long wait for unpopular books that don't have many lenders or books which are so popular that many people have already requested them. Also, BookLending.com sends out frequent emails with no opt-out option. However, you can set your email client to filter their bulk emails into their own folder so they don't clutter your inbox. You might want to read them, though, since they offer lists of good deals on Kindle books.
EReaderGirl provides regular lists of free and reduced books in the Christian, nonfiction and children's categories. You don't have to sign up for emails; just follow her on Twitter. This service comes to us from the writer of the popular Money Saving Mom blog, and her frequent updates mean that you get fresh content almost every day.
Visit Amazon.com's Kindle bestseller list and click on Top 100 Free to see Amazon's bestselling free Kindle books. You can also click on a category on the left to see the paid or free lists for numerous genres. Going through the paid list may net some nearly free books, since some cost $0.99 or $1.99. Sometimes, publishers even bundle together several books of the same author or genre into a set for only a dollar or two. Prices change constantly, so this list is worth checking frequently, especially for the avid reader.
Your local library may offer Kindle books through Overdrive. You can visit your library's Web site or call for more information, or even search Overdrive's Web site for participating libraries (click on Library Search). In addition to borrowing through your library's Web site and sending the Kindle book using Whispersync, you can also download Overdrive's free Android app and borrow books directly on your tablet or phone.
While the other options on this list don't cost anything to explore and work with any Kindle device or app - including computers and mobile devices running the free Kindle software - the Kindle Owners' Lending Library requires that you own a Kindle device and subscribe to Amazon Prime. If you have both of these, then the Lending Library can offer another source of free reading material, albeit one at a time and limited in scope. The Lending Library does cover many categories, though, and not just obscure books that few people would want to read.
