The Imperator Network uses the ShopChest plugin to manage and create shops across the world.
To create a shop, you need to place down a chest, and then hold the item you want to sell in your hand, and then run:
/shop create <amount> <buy-price> <sell-price>
amount is how many items should be sold per transaction,
buy-price is the cost for each transaction, and
sell-price is the amount you're willing to pay to receive said item (set
sell-price to 0 if you do not wish to allow others to sell to you)
To delete one of your shops, all you have to do is run
/shop remove and then right click on the shop you want to remove.
Imperator employs a custom
/market command to make it easier for buyers to find what they are looking for. It describes the average selling price for each item, and how to find the item.
To view the average prices of an item, simply do
/market. You can also do
/market <page-number> to view more items on multiple pages.
To view the exact coordinates of a shop selling an item, do
