noh + haunted ghosts crones for 540k, I'm inclined to not use this sale since it's so bulky - probably could be considered a quickbuy

precise trade is untraceable here, but adding up everything leaving buyer's compare, it works out surprisingly close to 400, so I would say it supports the pure sale.

Taking 400 flat.
