As Schultz puts it: "Our experience to-date confirms that once fully rolled out, Mobile Order and Pay will drive a significant increase in mobile payment transaction in our stores overall and have a flywheel positive effect on our overall business, driving both increased MSR membership and app usage and creating significant additional one-to-one marketing opportunities." Diversifying its product offerings Expanding outside of its core coffee offering and into both food and tea is another strategic initiative that should pay off for Starbucks in 2015. The company is already seeing an uptick in revenue from sales of tea beveragesin its stores, and management is confident it can double tea revenue to roughly $2 billion during the next five years. With the full integration of La Boulange, food is also driving sales growth for Starbucks outside of its core coffee business. In fact, food recently contributed 2% to Starbucks same-store sales growth for the fourth consecutive quarter.
