when does microsoft restock

do they actually restock or is it just gonna be sold out like

cmon surface book 2 1tb

You can get to checkout? My friend tried ordering one and it kept telling him to choose a different payment method even though his payment was good and cleared with his bank.

i ordered earlier today but i had to cancel bc it took my actual PP balance. but now 15/i7/1tb is out of stock. i will call tomorrow and order by phone or something.
