As it seeks to get a bigger slice of Americans' spending, Google just ramped up the delivery wars by expanding its same-day service.
The tech giant announced its Google Express service will serve three more cities—Chicago, Boston and Washington. It was already available in the San Francisco area, West Los Angeles and Manhattan.
Over the next couple months, 16 more companies will also join the list of stores available for same-day delivery, including Costco, Target, Staples and Whole Foods Market. Bay Area shoppers who are at least 21 years old can now order alcohol, too.
