Did you know signing up for the Starbucks Card Rewards program can get you a free coffee? I was oblivious until I saw signs at one of their stores 2 weeks ago. All you have to do is pick-up a Starbucks giftcard on your next visit and then register it online at Starbucks Card Rewards.
If you do this before July 14th, Starbucks will mail you a coupon for one free beverage. There are also some other perks [pun intended ;) ]. Check out their website for more details.
