I just updated some things in the chest shop system.
Sell items to chests
When creating a chest shop you can put the sell price next to the buy price.
Right click a sign like normally to
buy from the chest
Left click the sign to
sell items to the chest for the amount of gold on the sign.
This way, say you're looking to buy a lot of cobble for a new project. You can simply set up a chest where you buy 64 cobble for 2 gold :
B 0 : S 2
People can then pass by and simply click on the sign when they have cobble in the inventory and get cold, hard, gold from you.
Tracked stats
All transactions are saved to a database so we can keep track of daily/weekly/monthly rates, prices etc.

This information will most likely be public somewhere on the site (anonymous stats ofc.)
Max price
The max. price to all shops is now 100 G.
