Walmart just tried to undercut Amazon on, of all things, books. They’ve announced that they’re now selling the “top 10 pre-selling books” for $9 each, with free home delivery. Amazon has responded by dropping its price to $9 on the same titles, but their free shipping doesn’t kick in until you buy $25 worth of merchandise (or pay the annual fee for Amazon Prime). Price war!
