Cool food find: Free coffee

I know this is my second Starbucks post but how could I resist...

Starbucks is offering a complimentary brewed or iced coffee today, April 15th, if you bring your own reusable travel mug. This is to encourage customers to reduce waste during Earth Month and beyond. After that you'll get a 10 cent discount everytime you use your reusable mug.

I like to use my travel mug because my coffee stays hot. I'm a slow sipper and hate not being able to finish my coffee before it goes cold.
