Get a Free Cup of the Black Stuff at Starbucks by Going Green

Save a tree by bringing your own mug to Starbucks, and you'll be handsomely rewarded with a free fill-up.


In celebration of Earth Day, Starbucks is playing to its iconic green color with an eco-friendly initiative. Grab your reusable travel mug and head to your nearest Starbucks (if you're in a city like NewsFeed, you can probably see three from your office window). But in a crazy twist from usual – you can forget your wallet.

Starbucks will top up your cup with a brewed coffee or tea, on the house. The options are fewer than usual – hot or iced, coffee or tea, but the primary perk is that it comes at no cost.

The promotion is an attempt to get us to bring in reusable mugs in on a daily basis – but let's be honest, the deal is made much sweeter by the free java. While today the coffee is on their dime, any other day they will give you an actual dime off for bringing in your own mug.

Last year, Starbucks reports it filled more than 1.2 million mugs on Earth Day. Though we bet that number dropped substantially on April 23.
