But to get to my point quickly here, just think about making the admin shop at spawn, overpriced, so it can encourage player shop even more and let the player shops have a battle of prices. This will bring players to every shop presented at spawn, so every shop shall be visited in search for the cheapest

This will aslo help encourage Pri's number 2 or 3 idea of how to gain money. "Trading"
So in my opinion, there is plenty of positive outcome from this idea, but I am just one person, which has another agreeing with him. So, think about it, maybe have an open debate in the comments below, always interesting to see multiple peoples opinions about such things!
Looking forward to replies from everybody!

Now have a good night ^^
