Online bookseller Amazon.com has capitulated in a fight with a major publisher. After a standoff with MacMillan, Amazon has agreed to raise the prices of its e-books. MacMillan and other publishers don't like the prices Amazon has been charging â€” especially that $9.99 price tag for bestsellers. Publishers want to charge more. And they're in a stronger position, in part thanks to Apple, which entered the online bookselling world with its new iPad device.
