On iRO, this is localized as Buying Store.
Using a Purchase Shop
A maximum of 2 items at a time can be advertised in a shop (5 items for Merchant classes). Players must have one of the item they are seeking to purchase already in their inventory. Only certain items can be purchased through a Purchase Shop:
- Etc. Items
- Non-Brewed Consumable Items
Creating a Purchase Shop
Purchase Shops are created via different means based on what class the player is. Non-Merchant class characters must purchase Black Market Purchase Shop Licenses while Merchant-types open stores via the skill Open Purchase Shop much like a normal shop is opened via using the Vending skill.
