Well yeah.

If you're in Forest, and you need 90 stones, you order 90 stones for 180p. You set the price however you like. Then you mass out - Buying 90 stones for 180p in Wimnim West, Forest Island, and if anyone's interested they sell. If nobody's interested, anyone can check the shopkeepers for a list of things they're buying, and things their friends in other kingdom-shops are buying: The Dustari kingdomshopkeeper tells you you could get 180p for 90 stones if you go to Forest.

But that's a little complicated. As it stands, I got one (badly) working such that you sell anything to the shopkeeper and it goes on the table. You only get the standard NPCStore price, but then other people in your kingdom can buy it - granted, at the standard NPCStore price, but they can buy Remove Curse scrolls as long as some remain; they can buy Coal, Iron, Stone, Bread, stuff you don't usually find in shops but always need.
