Creating chest shops is a great way to earn money and collect resources.
You need a container and a sign to set up a shop. Valid containers are chests, double chests and barrels.
Place your container down and attach a sign to the front, on the sign you need to add the details of what you want to trade!
Chest Shop Format
After placing your sign, you will be prompted to right-click the sign with the item you are looking to trade.
If you are only looking to buy or sell items, you can only enter B 100 or S 50 like listed above.
Only one item can be traded per chest.
