Did you know you can publish your work on Amazon for free? As an experiment I recently published something I wrote about using self-exclusion programs to help people quit smoking.
Follow this link to see the book on Amazon.com.
It is an ebook, which means you need to download an ebook reader for your pc in order to read it. It costs $2.99, which is the least that Amazon would let me charge. I have seen essays on Amazon for $1.99, such as this one, but I am not sure how they managed that.
