Free coffee on Earth Day (April 22)

caribou Coffee_Earth Day Free Coffee ImageOn Earth Day, Caribou Coffee will be providing free coffee to those who bring in a reusable mug.

As a reminder, by bringing in a reusable mug or tumbler to your local Caribou Coffee or Starbucks year-round you will receive a 10 cent discount on your beverage.  Starbucks typically runs the same offer on Earth Day but I cannot find confirmation to that effect for this year.
