PlayBerry features a World Auction system that brings together every player trade offer on the server in a single interface. It lets you quickly find, compare, and purchase items without relying on private stores or offline shops.

The auction is accessed through the Trade Manager NPCs located in towns. Through them, players can browse the item catalog, buy gear and resources, and list their own goods for sale with a set price and listing duration. All listings are added to a shared pool and become available to the entire server.

Unlike classic High Five, where trading is limited to private stores and requires hunting down sellers, PlayBerry features a single, unified global marketplace.
