While preparing to go on vacation I was concerned about how to handle my publishing and book selling business. Sure, I'm online and so are my book sales, but I will still have to advertise and fulfill sales while gone.
I can't afford to hang a sign on my website saying, "Gone fishing, be back in two weeks". I don't think potential customers would understand. I don't think you can afford to do so either. So, what is a niche publisher to do?
