I got a call from a vanity press company one day. They said that one of their publishing packages would be $8000. I said, “Great, mail it over.” They said, “No, you have to pay us $8000 to publish with us.” “Why should I do that? I would be making you money if you published my book.” They replied, “The author of Fifty Shades of Grey paid to publish with a publisher like us and look how successful she became.” I hung up.
The best option would be, just don’t.
