On Tuesday, Amazon began announcing settlement payments to customers who bought e-books between April 2010 and May 2012. (Some less-literate Ars staffers, like Nate Anderson, got as little as $1, while others, like yours truly, got more than $48.)

The funds are coming from Apple as part of an antitrust lawsuit that was settled earlier this year.

“You don't have to do anything to claim your credit, we have already added it to your Amazon account," reads the e-mail. "We will automatically apply your available credit to your purchase of qualifying items through Amazon, an Amazon device or an Amazon app.”

As Ars reported previously, Apple will have to pay $400 million to e-book consumers and $50 million to the plaintiffs' lawyers under the terms of a settlement reached in 2014.

In 2012, Apple and five publishers (Penguin, HarperCollins, Hachette, Simon & Schuster, and Macmillan) were sued by the Department of Justice and 33 states’ attorney general offices for conspiring to offer e-books at a higher price than Amazon’s loss-leading $9.99. The publishers all eventually settled for a total of $166 million payable to states and consumers, but Apple held out and eventually lost a judgement in Manhattan federal court.
