I don't know the prices anymore, since I haven't been on in over a month I'd wager.
But; I suggest just farming for it, and not buying them.
The ingredients are crazy-easy to farm, and you can level up some low leveled-characters.
The books are mad-cheap, and the papers are probably the only thing that will come to a "signifigant" amount.
500-800G is a fair price per unit, since like I said, they're really easy to farm.
