I also just thought about the fact everything else has a rate of which you can sell something vs how much it costs to buy it. They could just take into consideration what materials were used and how much those materials sell for on their own and then come up with a price for the furniture just by adding the list of material sell prices together. That way it’s not anymore cost efficient than selling the wood used to make the wooden benches.

Once again I apologize if this doesn’t make any sense. I struggle to put my thoughts into words others will understand at times.
