Amazon has pledged to offer partial refunds on some Kindle book sales, after three publishers agreed, in principle, to settle a price-fixing anti-trust case.
The online giant emailed customers in the United States this weekend informing them they could receive between $0.30 and $1.32 (£.082) for each applicable Kindle ebook purchased between April 2010 and May 2012.
The refunds will be on books published by the HarperCollins, Simon & Schuster and Hachette, the three companies offering to settle the case brought against them, Apple and two-other publishers.
The settlement, which is still to be approved by the judge presiding over the case, would see the publishers set up a $69m fund from which the rebates would be distributed as Amazon account credit (or a personal cheque, if desired).
Amazon, which has been attempting to lower prices of ebooks for quite some-time, told customers: "In addition to the account credit, the settlements impose limitations on the publishers' ability to set e-book prices.
"We think these settlements are a big win for customers and look forward to lowering prices on more Kindle books in the future."
