Are the cola mailed out

You're referring to the Coca-Cola Freestyle machines!

Yes, the Coca-Cola Freestyle machines are designed to dispense a variety of flavors, including cola, in a unique way. Instead of using traditional syrup dispensers, the machines use a proprietary system that combines flavorings and sweeteners to create a customized drink.

When you select a flavor on the machine's touchscreen, it dispenses a precise amount of flavorings and sweeteners into a cup, which is then filled with carbonated water. This process allows for a wide range of flavors and combinations, including unique and limited-edition flavors.

The machines are typically found in restaurants, movie theaters, and other public places, and are designed to provide a fun and interactive experience for customers. So, to answer your question, the cola (or any other flavor) is not "mailed out" in the classical sense, but rather dispensed on-site through the machine!
