Although this is a boon for readers, they should also know that if this price war keeps up, many independent bookstores may be driven out of business -- and the brick and mortar chains may not be far behind. Also, the chances for a new author to get published in this kind of environment become infinitely more staggering than they already are.
While I welcome anything that makes books more accessible for readers, I think this may prove to be a short-sighted approach that ultimately hurts everyone. There truly is no such thing as a free lunch.
