It's all about the coffee, man

I paid Six dollars for a 32 ounce can of coffee. I pay $1.75 each morning for a 20 ounce cup of coffee at the gas station on the way to work every morning. The can of coffee I have at home, I calculated, is worth about fifty dollars in coffee sales. Minus the cost of buying the coffee, plus disposable cups, sweetner and creamer, I will save at least $40
