How to create a chest shop:
1. Place a chest on the ground
2. Place a sign on the chest and write:
- Line 1: Leave this line blank (It will automatically update with your username later)
- Line 2: Amount of items to buy or sell
- Line 3: Combination of Buy and Sell prices.
- Below is a screenshot of a chest shop where you can Buy 64 of an item for 100 or Sell 64 of an item for 50
- Line 4: A question mark (It will automatically update with your item of choice later)
3. Right click the sign with an item in hand to finish setting up the shop (Note that the first and last lines update when you right click the sign!)
Now anyone can buy 64 stone for 100 and sell them back for 50
