The basic setup would be a sign above a chest and would be setup in this way. First line: doesn't matter second line: Buyirt:3 Third Line: Sell:CobbleStone:3 This would work by having a double chest locked with a block on one side and a chest with Or a better configuration you can think of. This is for a server that doesn't use currency it uses bartering, this is why none of the other shop plugins that I have seen would work well or at all. tl;dr a chest based shop plugin that doesn't use any other plugins and lets you choose the sell/buy price on the sign. Thank you for reading and I hope some one can do this.
