How to use: Sign Shop

Supported Signs:
[Buy] - Buys an item fro the shop chest for the price specified on the 4th line
[Sell] - Sells an item to the shop chest for the price specified on the 4th line

1) Create a sign. Line 1 needs to be [Buy] (or whatever type of sign). Line 4 needs to be the price (aka 50, 50.25) of your item(s). lines 2&3 can describe your item(s), or be blank.

2) While holding redstone, click on the sign. (you should get a message)

3) Find a chest you want to use as your storage, put ONLY the items you want the sign to sell in it. For example, if you have a stack of 64 Cobblestone and want to sell two at a time, put only two in the chest.

3) Click on the chest with redstone. (you should get a message)
Put all of your cobblestone in the chest

4) Now players can click on your sign (no redstone needed), purchase the cobbletone two at a time! (right click to buy without confirmation dialog)

Note - One chest can maintain multiple signs, just take everything out and set the new sign up, then put all the items for both signs in so the shop has something to sell.
