(WashingtonPost) - Amazon.com, the nation’s largest online retailer, may soon be selling wine. The trade publication Wine Industry Insight reported on its Web site late last month that Amazon is recruiting wineries in California’s Napa and Sonoma counties for a new effort at online wine sales to launch before the Christmas shopping season. The wineries will handle the actual shipping, with Amazon leveraging its power to obtain favorable shipping rates from UPS, the report said.
