Attached is more foe a survival run, but it gives some idea of prices for things. I wanted to look up the price of fur for trade and it gave 20gp but that is for "a bolt of fur" so 10 large furs 6 lbs each. A reasonable fur from an hour of hunting could be 1/10th of that or 2gp retail. Of course that price is subject to change and may vary and your price to sell to a vendor would be at most half of that without a specific relationship. Also, they don't want raw fur, they want tanned and cleaned fur so that's extra work and requires skill which I lumped with butcher rather than having it's own "tanner's tools". No self respecting butcher would throw out the pelt, they would use the brain to make tannin and tan the hide for sale.

[Ashley] we're going crazy with an in-system survivalist run with economy and all that, making excel sheets and roll tables for all kinds of things no one will likely ever see.

Durability is another thing to consider but it never made sense to me to add it arbitrarily low, so in this campaign we will not have durability of things except if an attack or defense roll hits a natural 1 x3 times, then the quality of the item will decrease one step from Good to fair to patched to scrap and any stage can be repaired back to fair given the right proficiency or hired service. Magic weapons are immune to this as they always have a +1 or better which makes a natural 1 become 2. I will keep track of all this and let you know if and when your equipment is damaged.
