Well at 250 a qp he's paying 62.50 per ounce. (Probably shwag or low end mids even at bulk prices.) sooo he could try and sell it at 100 per ounce/50 a 1/2 and so on, making a profit of 37.50 per ounce. (150$ profit if he sells the full qp.)

BTW I've never dealt so I'm not too sure about that resale price.
