Starbucks Testing Mobile Stores on Campuses

Two big moves in the world of coffee, which, as Slate points out, come amid rising prices and shrinking bean supplies:

• Starbucks: The chain for the first time is borrowing a page from those ever-popular food trucks, reports the Seattle Times. Starbucks will have mobile stores on three college campuses this year—Arizona State University, James Madison University in Virginia, and Coastal Carolina University in South Carolina. The trucks will move around the campuses throughout the day, and if the idea works, expect to see more across the nation.

• McDonald's: The company plans to sell its McCafe brand of coffee in US supermarkets starting early next year, reports Reuters. The coffee will be available in 12-ounce packages, along with single-serving portions and K-cups. No word on price yet.

Meanwhile, the rest of the world favors instant coffee. (More Starbucks stories.)
