Here's a nice green freebie in honour of Earth Day. As in years past, Starbucks will offer a free cup of coffee to anyone who brings in a reusable mug of their own on April 22, 2009. Since this is being promoted on the Starbucks Canada page we're confident that Canadian Starbucks locations will participate.

If you're in the habit of bringing a reusable mug every day, Starbucks has an ongoing green initiative where you can receive 10 cents off your beverage when you bring your own mug.
