I've noticed that a lot of the time in Prisons, and presumably other gamemodes, though I mostly play Prisons, gods and invaders will sell their /fixes on various items. The reason for this is simple; they're in high demand, since repairing an item such as a heavily enchanted diamond pickaxe can be extremely expensive. However, I had a thought; implement a command called /renewal. This command would most likely be either daily or weekly. When a god/invader/other used it, it would instantly remove the extra expense of repairing an item using an anvil that repairing it before had added. I'm not sure of how this would work, but I'm certain the staff could make it do so if they decide to implement it. The name could, of course, be changed, but it makes sense so far as I am concerned.
