Vending Machine (Fallout: New Vegas)

Nuka-Cola Vending Machines are world objects and containers

Locations
In Fallout: New Vegas there are 42 located throughout the Mojave Wasteland, in various buildings. The contents of a vending machine are randomly set the first time the player character enters a map cell and remain that way for the rest of the game. In all other respects, it is a standard container and can be used for long term storage throughout the game.

A fully stocked vending machine contains nine bottle caps and three Nuka-Cola. The minimum a vending machine will contain is a single Nuka-Cola with the rest being random.
