McDonald's App - Caribe is the official McDonald's app for the Caribbean region. If you live in one of the countries in this area this is the app you should use to stay up to date on all the company's offers while getting access to special coupons.
The first thing to do if you want to access any kind of offer is register on the app, as only people with an account can access the discounts. Once inside you can take a look at the coupons, restaurants, and menus from McDonald's. In the first option there's a wide array of offers that let you enjoy McProducts while saving a bit of money. In the restaurants sections you can see where the closest McDonald's is to you, while in the menu section there's a list of all the products sold.
One of the cool things about the McDonald's App - Caribe is not only the discounts but also the nutritional values that you can check for each product and discover which options are available in case you have some kind of food allergy or intolerance.
To use the offers, open the coupon and tap on the QR code on each discount so it can be scanned at the register.
