So is Amazon Freight Services Bezos’s next mission? When I ask, the laugh lines vanish from his face as if someone flipped a switch on his back. He contends that same-day delivery is too expensive outside of urban markets and that it only makes sense for Amazon to deliver its own products within the Fresh program. In China, he explains, Amazon does in fact deliver products via many couriers and bicycle messengers. “But in a country like the United States,” he says, “we have such a sophisticated last-mile delivery system that it makes more sense for Amazon to use that system to reach its customers in a rapid and accurate way.” When I ask whether he would consider, say, buying UPS, with its 90,000 trucks—or even more radically, purchasing the foundering USPS, with its 213,000 vehicles running daily through America’s cities and towns—Bezos scoffs. But he won’t precisely say no.
