Pretty sure that's because the net-a-porter sale starts before mr.porters sale. Good looking out though, I never knew about that app. I'm sure we'll be able to do this with MrP once it gets closer to their sale!
I know, I have my shopping cart on their website full of their tees and sweatshirts. My only complaint about the black villain is my backpack is fading the color in some areas. But whatever, that's bound to happen with black terry.
