Not a lot of people will take this as a good thing but street tax should be a thing here.
If your the one selling an item and the trade doesn't happen through the consignment store, it should still be taxed. In not saying any certain % or anything right now, I'm merely saying it would be a healthy way to keep gold from devaluing.

An option to split tax between the two would be fair I think. I have more but would enjoy some constructive feedback first please!

Thank all and happy farming!
