Starbucks will begin delivering coffee and food in select markets next year, as part of its push to expand into e-commerce. CEO Howard Schultz revealed the company's plans during its quarterly earnings conference call yesterday, saying that the delivery service will be available to loyalty program members through a new Mobile Order and Pay app debuting later this year.

"Imagine the ability to create a standing order of Starbucks delivered hot to your desk daily," Schultz said. "That's our version of e-commerce on steroids."

Matt Ryan, Starbucks' global chief strategy officer, added that the delivery program is still in its "early days," though the company is "moving full speed ahead" with plans to introduce it during the second half of 2015. The service is the latest in a series of mobile-focused initiatives that Starbucks has launched recently, including its successful mobile payment app.
