Aftering getting a second wilderpick and bottomles bucket I decided to use the global chat and I auctioned them off. It went really well in my opinion and another person also took up the idea and did an auction. 

My Idea is that the server gets a plugin that lets people bid for things in chat. Maybe a weekly or every other week an auction goes on. I would also suggest if there is a way to do it that you can't make a bid unless you have the payment in your inventory. 

I think an event like an auction would be a good way to add to the shopping market and make it an interactive for buying items. 

I was here for this and it was fun! An auction night could be interesting. It did get a little crazy with people overlapping at a couple points, but overall it went very well.
