You can get a free medium Coke Zero drink from McDonald's. All you have to do is download the app on your phone which can be found here for Apple phone users (Log In) or here for Android users (Log In). The offer will be on the app, just go into the McDonalds store and show them the offer. The offer is valid from the 23rd of January to the 22nd of February. I believe it is a one time only use. Enjoy your drink
