Even though you can go to player shops and sell items, most to all don't want to buy mob drops like rotten flesh, spider eyes, etc, because they have no real use. I think it'd be a good idea to have a branch of the Empire shop for selling mob drops. This could help starting players accumulate rupees and players who hunt mobs regularly to sell drop items as opposed to just throwing them out. Some items would be worth more than others. For instance a mob head is rarer than gunpowder. Common drops would sell for very cheap but it's better than just throwing them away.
