yeah, just wondering why usually they are, for example when you cook a lobster, its price dacreases

Because people want skill capes, the only reason.

Because people buy the raw materials to up their skills. Example: Buy raw lobs to cook.

 

Once it's been cooked, less people want to buy.

 

Lobs in particular are used by skillers to raise cooking quite quickly. And theres a lot of people out to get 99 cooking as it's relatively quick anyway.

And a lot of the time the finished products aren't really that good anyways, there is no reason to get leather boots so therefore the price drop from the soft leather is dramatic.
