Answer:
Well...the market determines the price by how many are available and how rare the material is that's demanded. The less quantity there are for that object or food at the moment, the cost would be more. The more there is for that object or food the less you'd have to pay.
Explanation:
Less is more
More is less
Cycle repeats until they refresh stocks.
It also depends on factory branded items and non-branded items.
Of course if its branded, it'd cost more, and a percent of that would go back to the factory who's distributing to other markets. Which also costs the Market some money since they bought supplies from them in the first place.
