I am currently buying all stacks of dirt or grass for $5 each.
Collect as much as you want whether it is 1 stack or 100 doublechests of dirt/grass!
Then just send me a mail or a PM if I'm on for a TP and I'll purchase them all ^.^

P.S. - If you have any questions or such feel free to send me a PM on the forums or a message in game >.<
