On Saturday, Amazon started e-mailing its Kindle customers, alerting them to a possible credit coming their way courtesy of Hachette, Harper Collins, and Simon & Schuster. The three publishers were pulled into an antitrust suit in April by the Department of Justice, along with two other e-book publishers (Penguin and Macmillan) and Apple, as part of a massive antitrust case that started after the EU began investigating e-book prices. Sixteen states filed their own antitrust suits against the publishers and Apple as well.

"Hachette, Harper Collins, and Simon & Schuster have settled an antitrust lawsuit about e-book prices," Amazon’s notification reads. "Under the proposed settlements, the publishers will provide funds for a credit that will be applied directly to your Amazon.com account. If the Court approves the settlements, the account credit will appear automatically and can be used to purchase Kindle books or print books."

While the settlement still needs to be approved by the court at a hearing on February 8, 2013, Hachette, Harper Collins, and Simon & Schuster have already set up a $69 million fund to pay back customers. According to Amazon, customers can expect a credit in the range of $0.30 to $1.32 for each eligible e-book the customer bought between April 2010 and May 2012 on a Kindle. Customers can also request the credit in the form of a check.

The news of the settlement is in keeping with rumors earlier this year that three publishers were in talks to settle the lawsuits, although it was unclear which of the five were discussing the matter. Apple, Penguin, and Macmillan have not settled with the DoJ and will likely go to trial in 2013.

Amazon is clearly happy with the decision, as it notes at the end of its e-mail, "In addition to the account credit, the settlements impose limitations on the publishers’ ability to set e-book prices. We think these settlements are a big win for customers and look forward to lowering prices on more Kindle books in the future."
