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.
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 |
30 | Everywhere in South Underrail |
 United Stations Dollar |
50 | United Stations and Protectorate bases |
Restocking
Most merchant stores are restocked every 90 minutes. Higher level items or entirely new items will be available in some stores based on game progression. (e.g. TNT Charges in SGS armory)
Items bought
Traders usually buy only certain types of items, and only in limited amounts. Salesman feat increases the amount of items you can sell.
These limits reset when their inventory is restocked.
Special merchandise
As of version 1.0.2.2, certain merchants also have special merchandise 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.
