It's mentioned in the lawsuit which described how Apple orchestrated the publishing industry to raise its prices for Apple to have room to mandate a 30% share [1]
Amazon was selling eBooks at $9.99, for Apple it was an issue because they couldn't ask a 30% share from publishers AND compete at $9.99 because Amazon achieved that price due to wholesale volume-deals, and likely not with a 30%+ margin.
Publishers wanted Amazon to increase sales-prices from $9.99, but due to their wholesale model they couldn't dictate that. Even when they increased wholesale prices, Amazon kept their sales-price of many NYT bestsellers at $9.99 making a loss (probably to drive eReader growth).
Quote: "Amazon continued to sell books at $9.99, losing money, even when publishers increased the wholesale price of books they were giving the online giant."
