Walmart declares war on Amazon, slashes book prices -- again

It's a retailing clash of the titans: Brick-and-mortar giant Walmart (WMT) is going head-to-head with online retailer Amazon (AMZN) in a battle over prices for some of the hottest book titles this holiday season.

The shooting started Thursday when Walmart announced it would sell 10 hot new book releases -- including Under the Dome by Stephen King, Going Rogue: An American Life by Sarah Palin, I, Alex Cross by James Patterson, and Ford County: Stories by John Grisham -- for just $10 through Walmart.com.
