Hmm, if bones are in short supply, and you can sell a foot for two hundred bucks, I wonder how long it’ll take for the market to “correct” 
Sale on human ribs only $4 each! Get em while they’re hot!
You and you’re need to spend money on human bones! I just take what I need fresh from the fallen corpses of those who oppose me in battle.
I know I’d be pissed if my patella was on “special sale” for $10.00. Or if my skeleton got rated “C quality”.
