Remember that antitrust suit concerning publishers, ebooks and price rigging? The good news, at least if you bought one of the affected titles between April 2010 and May 2012, is that Amazon is sending some money your way. If the book you purchased had ever been a New York Times bestseller, then youll receive a credit of $3.17 in your Kindle account, but if the book was, erm, less popular, youll get $0.73.
