McDonald's celebrates National Coffee Day by offering free coffee on Sept. 29th

Tim Hortons isn't the only one giving away free coffee on National Coffee Day. McDonald's is offering a free cup of Premium Roast Coffee of any size if you order through the My McD's app. That's the only catch to secure one free cup. No, you can't get another one every time you order. It's limited to one free coffee per customer. And, unfortunately, the offer isn't available in Alberta, the Northwest Territories, and Lloydminster, Saskatchewan. But if you aren't in those areas and you want some free coffee, then use the app. It's available for free on the Apple App Store and the Google Play Store.
