If you want to buy a book they publish, you are a click away from bying it from http://www.barnesandnoble.com/ or from Apple if you want it on your ipad.
But if Amazon wants to sell it they have no choice but to get it from the conglomerate Hachette.
My favorite comment on this so far comes from Hugh Howey (author of the WOOL series)at http://www.huffingtonpost.com/hugh-howey/winning-at-monopoly...
From that article.
“The real monopoly, once you start examining business practices and attitudes, is Big Publishing itself,”
"Where is the outcry for Amazon-published authors who are blocked from sale by practically every brick and mortar store? It doesn't exist. The response is simply: That's what those authors get for signing with Amazon. Imagine an observer today saying, "That's what those authors get for signing with Hachette." The hypocrisy astounds."
