Buy Starbucks in the a.m., get a $2 drink in the p.m.

Wow, that was hard to condense down into a catchy headline. This offer is something called the "Treat Receipt" (scroll down to the bottom). When you make any purchase before 2:00 p.m., you can get any Grande cold beverage for $2 (plus tax) after 2:00 p.m. the same day, when you show your receipt.

The offer lasts until September 28 at participating stores, but enjoy it now, while it's still warm enough outside to make a Grande cold beverage a desirable thing.
