One more suggestion

[Dorign]

Hate me yet? :P

If a user has an item, say a weapon.. and they purchase another weapon before selling, they lose their money. Suggestion: either make it auto sell the item, or do not allow them to sell the item. :ninja:

It is supposed to auto sell the item, but considering this itemshop is about as carefully coded as something a drunk person did... :P
I'll see if I get around to fixing this, although I dislike writing code that will be redundant later (IE with the Inventory)

Well as I understand it, this is already pwned because the code is there. It just merges the equation of refund with the purchase of new items.
I added a couple of extra parenthesises, maybe that fixes the equation. If no change is noticed, then the bug report is labelled bogus :P

Maybe I just suck at math. :o
