How to create a shop on ByteUS.com Create shop:   Place a chest.   Place a sign 1 block near the chest (for example, above the chest)   On the sign, write:   Line 1: Your name Line 2: Quantity Line 3: Buy and/or Sell prices B = Buy price (others buy from you) S = Sell price (others sell to you) (If you have both B and S, separate them with a colon :) Line 4: Item name or ID Example: Player "AcrobotPL" wants to sell 64 diamonds for 10 money, and will buy them back from you for 5 money.   People won't be able to break chest, sign or the block the sign is on. Also, if you put "free" instead of price, it is free to buy or sell. Using shops:   Left-click to SELL to shop   Right-click to BUY from shop Destroying shops:   If you want to delete your old shop, simply SNEAK and destroy the sign. Stocking the shops:   You can either open the chest and stock it up, or click on your own sign - it will open chest's inventory.
