It's at least possible that every item in the merchant's list is equally likely and they just choose a certain number, but it's also possible that there are weights associated with items that affect probability. Saving the game before trading with her allows you to load that save for a different shipment, or you can wait/sleep for 48 hours. Unlike other merchants who offer shipments, Alexis Combes always has only one shipment available at any given time, but which item is in the shipment changes. The only solid reference to this I've found was on Nukapedia, referring to Alexis Combes' stock of shipments: For instance, sometimes Carla has duct tape. This is especially evident with junk merchants. In my experience, merchants don't always stock everything that they might stock. You have three highly related questions that I'll address separately:ĭo vendors restock on a random selection of items with some being more likely than others?
