Fallout 76 vendors

Background
Vendors can be found in various locations throughout Appalachia. Vendors, including those found in player C.A.M.P.s, are the primary source of buying and selling goods in the wasteland.
 * All NPC vendors in the world share a combined cap pool of 1,400 caps, or 2,800 during a Caps-a-Plenty weekend. This cap pool is reset after 20 real-time hours after you first sell an item after the previous reset.
 * The available caps vendors have access to is character-based. Switching to another server will not show a different amount of available caps.
 * Buying an item from a vendor will add one quarter of the buy price to the vendors' available caps, but it can not exceed the maximum of 1,400.
 * Vendors' inventory are server based. Switching to another server will show different inventory.
 * Vendors' inventory is not internally shared among the faction. Each vendor, including those of the same faction, will have different inventory.
 * Unlike vendors in previous games, sales and purchases are done one at a time, rather than having the player select the items they want to buy and/or select the items that they want to sell and then confirming the transaction. As vendors don't give credit, it is no longer possible to buy items with a value in excess of the players caps by also selling items to the merchant in the same transaction.
 * NPC vendors can neither be engaged in combat nor harmed.
 * If player A sells items to a vendor and player B subsequently trades with that vendor, those items will be available for player B to purchase.

Vending machines
Vending machines act as vendors, but the player cannot sell items. The Legendary exchange machine may only be sold to, but allows buybacks on items at a full refund. The Gold press machine may only be sold to, and all sales are final.
