This also means the many different Vendors at The Whitespring Resort all share the same stash of Caps.
Note that it also appears that Vendor Bots can share their maximum caps allowance between others of their faction - so after emptying the Vendor's coffers at Flatwoods, you may not be able to sell more to the Vendor at Morgantown Station until their coffers replenish. Many of these robots are found at various Train Stations, or abandoned faction bases. Trading Vendors are in short supply in Appalachia, but they do exist.
