Tomorrow, July 4th, you can get a free tall hot brewed coffee at your local Starbucks!
From their Facebook Event page: To spark the conversation in our stores, your local Starbucks will proudly serve everyone a free tall hot brewed coffee on the Fourth of July. (Participating stores only. 1 per person. Clover brewed coffees excluded.)
No coupon is needed, but I'd call your Starbucks before going in to see if they are participating.
