Starbucks is currently running a promo through 10/11, when you buy a coffee for a friend you get a free coffee.
“Our customers do amazing things everyday. A customer buys the next person in line their favorite beverage—not as an act of charity or thanks—but an acknowledgement of commonality and humanity. The gesture is small, but the act is endlessly inspiring.
In times like these, small acts of civility like these make a big difference. With that, we are extending a gesture. If you come into Starbucks and buy someone else their favorite beverage, we’ll give you a free tall brewed coffee.”
