I wrote a few cooking books a few years ago, and put them on Kindle. I didn't think I'd travel the world with them, but I thought they were decent little cooking books and might make something. Nothing. I sold less than 5, and lowered the price to $1 or $2. I'm surprised because it's a decent niche of a diet that a lot of people are turning to!
