Time to go buy a book. Email I just received:
Good news! You are entitled to an additional credit of $7.32 for some of your past Kindle book purchases. The credit results from legal settlements reached with publishers Hachette, HarperCollins, Simon & Schuster, Macmillan, and Penguin in antitrust lawsuits filed by State Attorneys General and Class Plaintiffs about the price of eBooks. This credit is in addition to the credit that you received from these settlements in March 2014.
