So, whenever I go to Starbucks, I order a tall cup of pike place roast. I ask them to put it into a larger cup so I can add milk and sugar.
I get a free flavoring and free refills because I have a "free" registered card. My drinks add up to another free drink.
FYI: You can get a $1 cup of coffee at most fast food restaurants. So, I rationalize that by getting a free refill, it is about the same.
