Decidedly great , unrealistically low prices on the Canadian HP side. I which we in Europe would have some , of , any of the rebates, specials etc that the US and Canada enjoy.
In Europe you'd pay the same for the 9180's cartridges alone.
There are many reasons for many users to want a Z at that price too. Just getting into such a system is brought into line with such a promotion that it makes sense if you have room to have a Z to use it for it's large capacity ink carts, spectro etc.
