TOPIC: [MC] Suggestion: Shop/Economy System

Server Name: ZARPGaming Minecraft
Suggestion Title: Shop/Economy System
Suggestion Details:Well basically as the title says I would like there to be a shop or economy system that would allow players to spend their Imperial Coins. I am not sure which plugin the money is using so I can't suggest any shop systems but if possible I would like to be able to sell and buy items for example stacks of blocks or other items. Obviously the prices of items could be priced high so that players are faced with the choice of farming mobs or selling items for the money or actually earning them. I wouldn't want it to be a straight simple choice between buying a stack of glowstone or digging dirt to create a stack.
How would it benefit the server: Would create a use for the currently useless Imperial Coins and allow players to spend time doing what they have fun with for example a player that enjoys mining can still buy TNT blocks to mine without having to go and dig up loads of gravel and sand to make it.
Potential Issues/Exploits: If the pricing is not fair then players will simply farm certain items to sell to purchase harder to acquire items. For example if players could sell dirt stacks for 200 Imperial Coins and buy a stack of TNT for 100 then it is obviously exploitable.
Additional notes: I am not too bothered how high the prices are as long as we get the option to use Imperial Coins for something like this. Also this would not be something to completely replace gathering the resources themselves it would simply be for those players who are in a rush and would rather purchase it with the coins they got from farming mobs or selling items, this is why the prices should be set carefully if accepted into the server. I don't know if this idea or suggestion was planned to be added or not so I made this anyway.
