The free coffee promotion starts Tuesday, September 16, 2014 and runs through Monday, September 29, 2014 at participating McDonald's restaurants nationwide. During the promotion, you can claim a free small McCafe coffee during breakfast hours.
McDonald's also ran a similar free coffee deal earlier this year back in March.
If you're a huge fan of McDonald's coffee, you might also be pleased to know that they've joined up with Kraft to package whole bean, ground, and single cup McCafe coffee and will be offering it in grocery stores nationwide beginning early next year.
