When I set up my free days, I wanted five in a row, but somehow I got the impression that Amazon only gave me four. Well, they did give me five, which means the book is still free today, which I guess is good because I forgot to take down the FREE FREE OMG FREE! line on the Web site until today (oops).
Anyway, no huge shock here, but remove the advertising and the number of books sold plummets. It's funny because I was just telling the older niece that people think the key to selling books is writing a good one, and that's just not true: Marketing leads to sales.
