Yesterday, Amazon sent out emails saying that money was credited to customers' accounts and no, that was not a mistake or a scam.

Amazon credited accounts based on the Apple E-books Settlement--don't jump for joy too yet, it's not that much money you'll get. According to NBC, the settlement

addressed the question of whether Apple and the five listed publishers conspired to fix and raise the retail prices of eBooks."

If you bought a Kindle from Hachette, HarperCollins, Macmillan, Penguin or Simon & Schuster during a certain time period, you saw some money come your way yesterday. Actually, Amazon was not even in the lawsuit, but because they have over 80% of online book industry, the opted to distribute money to the customers.
