If you go to McDonald’s, you can now get a free medium fry with your purchase. Here is how you do this: 

For starters, you must have the official McDonald’s ordering app from the App Store on your iPhone and then make a purchase of $1 or more and then pay with Apple Pay in the app in order to get your medium order of french fries.

This offer will be going until the end of September, so take advantage of this while you can because this is one tasty deal!
