Burger King came up with an interesting promotion to market their Whoppers. If you order their famous burger at McDonald’s, you will only pay a penny for it? Wait, what? You go through the golden arches drive-thru to get it. Nope.
If you open their app within 600 feet of a Mickey D’s and order the flame grilled awesomeness, you then drive to BK and pay a whole cent for it.
Not a bad deal. If you have both fast food restaurants near you and near each other.
