One of the best things about Amazon's Kindle system is that many popular books are offered completely free of charge during brief promotional periods. If you manage to find and download a book while it's offered free, it's yours to keep -- forever.

It's a great way to sample a new genre, or perhaps discover an author you hadn't noticed before. The free promotions usually last only a few days, but there's a new crop every day. You'll be amazed at the wealth of great books. Usually there are several hundred freebies in virtually every category of fiction and nonfiction, every day of the year. And these aren't just the dogs that nobody wants, the selection includes bona-fide bestsellers from the most famous authors in the world. You may never have to pay for a book again!

This book will introduce you to KindleBuffet.com, a website and newsletter founded by author Steve Weber to showcase the best Kindle books currently offered free -- plus a multitude of other avenues toward great free content.
