E-mail from Amazon

I received an e-mail notice from Amazon.com on Saturday that begins like this:

Dear Kindle Customer,

We have good news. You are entitled to a credit for some of your past e-book purchases as a result of legal settlements between several major e-book publishers and the Attorneys General of most U.S. states and territories, including yours. You do not need to do anything to receive this credit.
...
While we will not know the amount of your credit until the Court approves the settlements, the Attorneys General estimate that it will range from $0.30 to $1.32 for every eligible Kindle book that you purchased between April 2010 and May 2012.

Woo hoo, I'm thinking this may come out to about 1 free e-book.
