Chest and NPC Shops
Chest shops use a sign plus chest and distinguish player shops from administrative shops. Permissions include dkconfig.chestshop.create and dkconfig.chestshop.admin. Transactions depend on the selected economy and protection modules. DKConfig also contains an NPC-shop module for GUI/entity-based commerce.
When a shop cannot be used, check claim/area interaction permissions, sign format, stock, owner balance and economy integration. Avoid running two chest-shop listeners on the same sign format unless their priorities and materials are deliberately separated.
