Apple and four major European publishers are offering to sell ebooks at a discount in an attempt to end an EU antitrust investigation into price-fixing. The news comes from an unnamed source at Reuters, who adds that the discount would last for two years. The publishers, which include giants like Harper Collins and Simon & Schuster, were accused of colluding to fix ebook pricing at a certain level instead of competing, possibly "with the help of Apple." According to Reuters, the deal specified that other retailers, such as Amazon, could not sell the books at a lower price.
