I seriously almost sold a Magical Waterbowl for $20. Not USD, Ala money. I meant to put 20 bones. If I hadn't had seen it when I was editing my shop front, I would have wasted 20 bones AGAIN (I didn't want to buy the waterbowl in the first place).

I'm suggesting caps or bolded font for Bone Price listing so players see where they're entering it
Space between the two boxes, just a bit to separate them enough to know you didn't accidentally go to the game money slot to put a rare item at 10 bones and it show up at $10

And a conformation pop up. To seal the deal. It says
"Are you sure you want to sell -item name- for $0 and 24 bones?"
