Well let's start with the flathead it would be from down south and would probably be the pre cut stuff which wholesale is usually around $30kg if it was local dusky which is dearer wholesale boned and skinned it's fillet return is terrible and therefore dearer, Aussie barra depending whether farmed or wild which is dearer more than likely farmed its going to cost mid twenties to cut from wholesale, nobby snapper is one of the worst around $30kg to cut chances are if it was woolies though it was probably nannygai sold as snapper which is cheaper as far as prawns most in woolies is imported or farmed which probably cost anywhere up to $20 wholesale, but when you take into account paying for staff,leasing a place phenomenal amounts of water, electricity to make ice, then you have thrown out product the margin is a dismal that even gets worse when selling wholesale to restraunts that's even if they pay you most go bust eventually in the time I've been working at least five of my buyers have gone belly up and hundreds of restraunts it would have to be one of the worst business to be involved in I wouldn't do it.
