McDonald’s is celebrating the Rockies home opener with “a steal.” Today, Friday, April 7, they’re giving away a FREE McDouble at participating locations. No purchase necessary. However, there is one catch. (No pun intended.) You must download the McDonald’s app to get the required digital coupon. To download the app, click here. (The deal was announced via McDonald’s Colorado’s Twitter account.) Unfortunately, if you don’t have a smartphone or mobile device, you’re out of luck on this deal. (I’m such a cheapskate that I don’t even own a smartphone, so I know your pain, fellow flip phone owners!) Go, Rockies!
