Shops

As an Aristo, players can make personal shops.

You make a shop by placing a sign over a chest. The size of the chest doesn't matter. On the sign, use this format: There is an example format on the right.
 * 1) 
 * 2) 
 * b : s
 * 1) 

To use the shop correctly, after placing the sign, fill the chest under the sign with the item that you mentioned. If you're selling diamond on the sign, put diamonds.

Another convenient feature: if you have a large chest, you can use two shops on it. Simply do the above for both spaces over the chest. You can place both types of items in the same chest. If the chest runs out of items, and players attempt to by from it, the shop will notify the player that the shop is out of stock.

You can also use a single transaction method for line 3. Instead of putting "b : s", You could just put one side of the colon, like "b " or " s". I'm not certain, but I don't think the format of the price is specific. You could use any of the following:
 * b : s
 * b :s
 * s : b
 * s :b
 * b:s
 * s:b
