Sunday is National Coffee Day.
More than 400 billion cups of coffee are consumed each year — a world commodity that is second only to oil.
To celebrate, some national coffee businesses are offering free or discounted cups of Joe.
Krispy Kreme is celebrating by offering a free 12-ounce cup of its house blend coffee to customers across the nation. There's no purchase necessary.
Dunkin' Donuts is also celebrating with a free small hot or iced Dunkin' Donuts coffee at participating restaurants throughout the United States. The offer is available and redeemable only on National Coffee Day through the "My Offers" tab of the Dunkin' Mobile® App, which is available for both iPhone® and Android™ mobile devices.
