The online giant is reported to be planning a settlement with European Commission regulators in an antitrust probe.
Amazon may be looking to end accusations that it's abusing its dominance of the e-book market.
The European Commission is investigating Amazon over the bookseller's contracts with e-book publishers. Reuters quotes an unnamed source that Amazon is in talks with investigators to make concessions rather than wait for a potential fine to be imposed.
Europe's competition regulators began the investigation in June last year. They're focused on e-books in Europe, specifically those published in English and German.
The regulator launched a similar antitrust investigation in 2011 against Apple and five publishers, which was settled when the companies in question made concessions to European authorities. In the US, the same price-fixing case saw Apple hit with millions of dollars in damages. In June, some e-book readers began to be given credit as compensation for overpaying for e-books in the past.
