Sure bestsellers are loss leaders. But, do any of us know the economics behind the other 249,900 titles? No we don't. I speculate that for every loss Amazon takes on a bestseller they make two back on their other books. Books out in print for ten years for 9.99, want to bet there is a loss there. Lastly, a boycott is the best thing consumers can do. Anyone who ridicules it is obviously in need of being retaught business basics.
P.S. I am not a troll, rather someone who is passionate about what I believe in.
