Free Coke Zero at McDonald’s
Download the McDonald's app by clicking below and then log in or sign up to get a free medium Coke Zero.
We tried this and initially it didn't come up with anything, but after 10 minutes when we reopened the app the offer was there, so don't worry!
Then just order it through the app to get your freebie.
If you combine it with this offer you can get a burger, chips and a drink for £1.99.
