So I was clearing out my inventory and sold a coin purse to a merchant.
I came back later to do some more business and noticed I didn't see him having any gold in his inventory, even though he has 32k gold listed.
I saw it all went into that coin purse I sold him previously.
The problem is:
A) I can't get change back from any sales so I have to match item prices to trade
B) I can pick pocket that whole 32k since its only worth 20 gold, aka not counting the gold in the purse.
