Just a few days after a federal judge approved a settlement offer by several major book publishers who were sued for allegedly fixing the prices of ebooks, Amazon has already begun discounting titles from one of the publishers. A number of ebooks from HarperCollins — which was part of the settlement along with Hachette and Simon & Schuster — are being offered at discounted prices, with an Amazon spokesperson confirming to paidContent that "we are happy to again be lowering prices on a broad assortment of HarperCollins titles."

There's no word yet on whether or not ebooks from the other two publishers will start being discounted as well. While it may seem like things moved very fast, it shouldn't be too surprising that the deal was made quickly — when the settlement was initially reported last Friday, Amazon's Jay Marine told Reuters that ebook prices would be going down "soon." We've reached out to Amazon for more information about the changes and will update should we hear back.
