Help save the earth and get a free coffee! Bring your reusable go-cup to Starbucks on April 15, and they'll fill it with piping-hot, planet-loving brew for free. Starbucks goes through 3 billion paper cups and 1 billion plastic cups a year - not including all those bottled and canned drinks they sell.
I bet that would be 0.5 billion if they didn't always double-up on the paper cups to provide insulation and a heat buffer between your delicate hand and the scalding-hot coffee. Maybe I'll put that in the suggestion box while I'm enjoying my free coffee on Thursday.
