Merchant properties
Prices
The price modifier for items you purchase usually starts at 200% and can be lowered with your mercantile skill. Some traders may also offer you better deals than others.
Price is reduced by 1% (from the starting 200%) per point of mercantile skill. There's a cap on how much item prices can be reduced but there's no information available about this cap. It could be a soft cap that reduces the value of each point invested in mercantile or it could be a hard cap that prevents items from being sold for less than 115% of their base cost. (This information was deduced from screenshots posted here: https://steamcommunity.com/app/250520/discussions/0/2952595757894745888/)
Currency is always valued at its base value, without any price modifiers. Traders usually only accept local currencies in trade.
| Currency | Value | Accepted in |
 SGS Credits |
10 | South Gate Station (local currency) |
 Stygian Coin (Charons) |
30 | Everywhere in South Underrail |
 United Stations Dollar |
50 | United Stations and Protectorate bases |
 Zlatortiya |
15 | Nowhere in South Underrail, but Kokoschka exchanges it to stygian coins |
Restocking
Most merchant stores are restocked every 90 minutes.
Items bought
Traders usually buy only certain types of items, and only in limited amounts. Merchants also have limited amount of money available. These limits reset when their inventory is restocked.
Salesman feat increases the amount of items you can sell and Major Supplier feat increases the amount of money that merchants are willing to spend buying from you.
Merchandise shipments
All merchants start with an initial merchandise shipment, but may acquire new shipments (or lose access to some shipments) during the game to change their store inventory. New shipments with higher level items or entirely new items will be available in some stores based on game progression (e.g. TNT Charges in SGS armory after the railroad blockade is cleared) and special merchandise shipments are available to players who invest in mercantile skill.
Special merchandise
As of version 1.0.2.2, certain merchants have special merchandise shipments available to characters with mercantile skill. See Category: Special merchants for a list of these merchants.
Special merchandise includes more and better quality components and equipment. Special merchandise comes in multiple tiers with increasing skill requirements each. In future versions, special merchandise may even include unique items that cannot be gained otherwise.
