McDonald’s is offering $4 off a $4+ order when you download the McDonald’s App and join the rewards program.
We use our McDonalds app all the time! It is a great way to order the food and have it waiting on you when you arrive. I really dislike having to wait at McDonalds, so I order it on the app and then say I have arrived a few minutes before I am due to get there. I always find my food waiting on me when I get there.
