Wal-Mart Stores (WMT) has slashed book prices online, reducing the "10 pre-selling books on its website" to $10 apiece--sweetening the deal with free shipping.

Here's some perspective on that price point, from Reuters: "The $10 price represent a 66 percent cut on the $28.99 listing price for Sarah Palin's "Going Rogue: An American Life", or a 64 percent cut on the $27.99 price for Michael Crichton's 'Pirate Latitudes.' The titles will not ship until November, but eager consumers can now place orders for the books online -- representing 'pre-sales.'"

In addition, the article also explains how site will also launch a new feature called "America's Reading List," where they will list the 200 bestsellers and cut the list price in half for these books. (Via Publishers Weekly)
