Via Bud. Read it all here. Money quote:
According to The Bookseller.com Amazon is fighting with Hachette Livre to extract more discounts from the publisher and has REMOVED THE BUY BUTTON from their titles on the site (this is, I understand, on the UK Website). Can you imagine walking into your favorite bookstore, picking up a title and heading to the cash register and being told “No. We won’t sell you that book. The publisher hasn’t given us a big enough discount.” I would walk out and never come back.
Never go back, my friends.
