You all can now open your own trading area in your base or outside your base where ever you wish it.

How to Create a Shop
  1. Place a chest on the ground
  2. Sneak left click the chest with the item you want to trade
  3. Type in price for the item (As prompted) in chat
  4. Fill the chest with the items you wish to sell

Face the chest
Type either /qs sell or /qs buy to make the shop buy/sell instead (Optional: use /shop instead of /qs)
Stock the shop accordingly, if necessary.

Type /qs in game to get help
