Hundreds of thousands of e-book readers are due a part $2.6 million in refunds from settlements in an alleged price-fixing scheme.
The U.S. Department of Justice alleged that Amazon, Barnes & Noble among others conspired to raise the retail prices of e-books.
Apple was later found to have violated antitrust laws, and is currently appealing that decision.
Those due a refund should have been notified by email.
The refunds range from about $0.73 to $3.17 per e-book.
