Not that I ever saw. Only place that tells you anything is the merchant screens and they give you maybe 20 or 25% or what it is worth.
Heck they do not even give you refunds if you exit their store and come right back in 5 seconds later. They only give you that measly amount above.
Bunch of rip-off artists, I should report them to the BBB.

Money is not really important at all in this game anyways. I only used it for enchanting and that is cheap. Everything else I got from loot including all my potions, that I hardly ever used. I just ended up destroying most of my potions as when you get to 50 it starts taking up a new slot and the potions add up fast being in almost every loot.
Never used a strength, intelligence or dexterity potion throughout the whole game so it was a waste even collecting them in my case.
