The booksellers today began doling out credits as part of an antitrust case settlement against several publishers.
Amazon.com Inc. and Barnes & Noble Inc. have sent consumers who bought its e-books between April 1, 2010, and May 21, 2012, an e-mail alerting them that they have received a credit as part of a settlement between some of the largest U.S. book publishers and a coalition of state attorneys general.
