Fallout 76 vendors

Background
Merchants can be found in various locations throughout Appalachia. Merchants, along with other player characters, are the primary source of buying and selling goods within Appalachia. Merchants can neither be engaged in combat nor harmed.
 * Vendors' inventory are server based. Switching to another server will show different inventory.
 * Vendors share a combined cap pool of 1,400 caps which is shared across all factions. This cap pool is reset after 20 real-time hours.
 * The available caps vendors have access to is character-based. Switching to another server will not show a different amount of available caps.
 * Vendors' inventory is not internally shared among the faction. Vendors of the same faction will have different inventory.
 * Unlike merchants in previous games, sales and purchases are done one at a time, without the option to sell a large item in exchange for several lesser priced items. The vendor doesn't give credit, so unless you can buy the item outright, you'll need to either have enough caps on hand to make the sale, or come back later when you're a little richer.

Vending machines
Vending machines act as merchants that sell various items to the player characters.
