I need as much cobble as you can sell for this project: http://www.ecocitycraft.com/forum/viewtopic.php?f=813&t=31746

I buy cobble at .07 per piece if you only have a few stacks
I buy a double chest of cobble at 250 per double chest
I buy 5 double chests for 2k

As you can see, the prices start out at 2 cents above server price, and get considerably large the more is provided. Pm me if you're interested.
