Which form of retailing is Best Buy now using in airports to distribute its mobile phone and computer accessories, digital cameras, flash drives, and other consumer electronics?

In the different airports throughout the United States, Best Buy has installed an automatic sales system, through which vending machines that have different electronic devices are installed, whose products can be purchased by people who are in said airports, with no need to physically go to the store. That is, it is a vending machine for electronic items, whose function is to provide products that may be necessary before making a trip (headphones, chargers, etc.) in a fast and automated way.
