I believe that at different times of the day or week we have a sale. For example we raise the price of cobble to like 50 a stack to make a little quick money and make the server a little more fun. I have seen this on a different server before and I thought it was very cool and could transfer the idea to ECC. Also, I think now that pumpkins have gone down, mining prices should go up. Most every person that farmed, used pumpkins. Mining doesnt make very much money atm so I think the prices need to go up and the user set diamond prices go up too. This makes it so not all the population of ECC are farmers.
