Where are the Apple Samsung 1TB pcie Flash SSD?

Does anyone know where I can buy an Apple Flash Samsung 1TB pcie flash drive for Macbook Pro Retina late 2013 - 2014, model number MZ-KPU1T0T/0A6? They seem to be very hard to find.

i Do actually.....but it might not be the most convenient for you. Maybe you can try to mail them see if they ship it to your neck of the woods SSD 1.0TB Samsung 840 Evo
Good luck.
