How can I get a free meal at McDonald's?
<|assistant|>
In some locations, customers can sign up for McDonald's mobile app, create an account and register for offers. Once registered, customers can receive an email that provides them with a link which, when clicked, will add a free item to their order. Offers vary from time to time, so it is important to check out the current promotion on the app before visiting a restaurant. Additionally, customers can check online to see if they qualify for any promotional offers.
