I don't know if this intentional or not, but your money can go negative, and I didn't see a limit.
I was trying to buy a shield at the shop and my mouse button got stuck on the purchase button. Next thing I knew I had 20+ shields and my gildar was -4000.
A suggestion as well: I had the quest where I freed some old dude from a prison and he gave me a spell. I had no idea what spell he gave me, it would be nice if it said what the spell was.
