[FREE] SignMarket [1.16.5 - 1.21] - Sign and chest shops with hanging sign support, no database

SignMarket turns a sign on a chest into a working shop. Write [Buy] or [Sell], the amount, the price and the item, then right-click to trade. Shops are stored in the sign itself, so there is no database to set up and nothing to load on restart. Works with Vault, or with no economy plugin at all using an item as currency.

Features

• Sign and chest shops - Place a sign on or next to a chest, barrel or shulker box and write four lines to open a shop. Right-click to buy or sell.
• Hanging sign support - Hanging signs work as shops on 1.20 and newer, not just wall and standing signs. Most shop plugins still ignore them.
• No database - Every shop lives in the sign's own NBT. Nothing to install, nothing to migrate, and shops survive restarts on their own.
• Vault or item currency - Uses Vault when an economy plugin is present, otherwise pays in a configurable item such as diamonds. Player-shop earnings are kept inside the shop chest, so they work while the owner is offline.
• Admin shops - Mark a sign [Admin Buy] or [Admin Sell] for an infinite-stock server shop that needs no chest and no owner balance.
• Built-in protection - Shop signs and their containers cannot be broken by other players or destroyed by creeper and TNT explosions.

Commands

• /signshop <help|info|reload> - SignMarket management command.
