If you purchased an e-book on Amazon between April 1, 2010 and May 21, 2012, check your inbox. You may have received a credit for a Kindle e-book purchase.

You might be thinking, I already got this credit. Back in June of 2016, millions of Americans got free credits as part of an antitrust lawsuit brought against Apple. As part of the settlement, Apple agreed to issue $400 million in credits to millions of users in the form of credits on Amazon, Barnes & Noble, iTunes, Kobo, and others. Those credits expired in June 2017.

The good news is that as part of the settlement, e-book buyers are getting one more round of refunds, starting today.

If you purchased Amazon Kindle e-books between 2010 and 2012, you should be notified by email that you have another credit. Just in case you want to double-check to see if you were eligible for one, you can visit this page and login.

These new Amazon credits will expire April 20, 2018.

If you’re a Barnes & Noble e-book customer, you might also have a credit, too. Those customers were also emailed today and will receive either credits or postcard checks in the mail. The deadline to use your credit or cash your settlement check is the same: April 20, 2018. Check your Barnes & Noble account if you didn’t receive an email.

If you bought e-books on any other platform, you can find instructions and more information on the settlement website.

Wondering why you’re getting credits from Apple on sites like Amazon and Barnes & Noble? Back in 2009, Apple was getting into the e-book game and let publishers set their own prices on their site, which increased prices on sites like Amazon and Barnes & Noble. So when you bought e-books during this time period on Amazon and others, you were actually buying books with inflated prices.
