I've done the brick and mortar self-publishing, for non-fiction books. It worked out pretty well for me, and I made a few thousand dollars. It also took me almost a year to get my book out, from when I started writing it.
After numerous requests, I've decided to go ahead and make many of my stories availalbe for purchase. The first dozen of so ebooks will be updated, edited and extended version of many of the stories my readers are already familiar with.
