That guy's had that listing up for quite a while now, and keeps relisting it, lowering the price along the way. When he first listed it, I contacted him about selling just the keyboard, and mentioned that it would save him a lot in shipping costs, but he said no and said that shipping such a large item was no big deal, lol.
I suppose that's somewhat true. Shipping something like that is no big deal, but having that shipment arrive undamaged at its destination is often an entirely different story.
