"Amazon (NSDQ:AMZN - News) has turned off the buy button on nearly 5,000 Kindle titles from distributor Independent Publishers Group after IPG refused to capitulate to Amazon’s demand for better terms."
This article speaks for itself. Amazon's trying to force worse commissions on an alliance of independent publishers, and they won't agree to it. Interesting. It does seem that Amazon spends a lot of time fighting with publishers (big and small).
