Depends on what you mean by that, but if it's about getting lower prices, the consumer probably "lost" more than a decade ago.

I don't have an opinion on how freshly published best-sellers should be sold, to me it's the same as new movies going into theaters...I personally don't care and will wait for the home/digital version. It's not like it will rot in place.

Amazon can still lower price on old books if they really want to. All in all it's about dirty plays between (big) dirty players, and regulators are mostly running around closing loopholes.
