Long yammering short, I was looking through the list of shops, looking for some way I could put in a "General Munitions Depot" but there wasn't a single shop that was free out of all sixteen slots. Is there one of them that we could free up for a "General store" or something? Like, ... 30 arrows for $30, 20 bombs for $40, or a blue medicine worth $50? Perhaps some other supplies?

Remember, our normal keys (Non-level specific, non-boss, etc.) are going to have the appearance of lockpicks, and as far as I recall, only the King Of Thieves will be selling them. So far, Shop #13, 9, 3, and 1 are selling them. Any particular reason in mind?
