Starbucks is giving out free coffee to anyone who shows up with a clean, reusable cup.  It just has to be 20 ounces or less.  You can also sign up online to get a free seven-ounce, sample-size bag of Starbucks coffee in the mail.  (The reusable cup deal is at “participating locations,” but that’s usually most of them.)

Dunkin’ Perks members can get a free medium coffee with any purchase.

Panera is giving parents and caregivers UNLIMITED free coffee today.  Just let them know, and they won’t charge you.
