ChestShop signs can now be converted to SignShop signs. Simply add the amount of the item for a single transaction into the ChestShop chest, and punch the ChestShop sign and chest with redstone. Signshop will take care of the rest. Note: this does not yet work with ChestShop signs that do 2 transactions in one sign (e.g. the third line says "B 10:5 S".
