McDonald’s is working hard to get people back in the drive-thru. How are they doing it? With FREE fries. That’s right every Friday McDonald’s is giving away a free medium fry when you make a $1 purchase. Just download the McDonald’s app and place your $1 order and the free fries are automatically added to your order. You have to act fast tho because the offer will only be valid through June 28th T.G.I.F!
