How can I order more than two iphone 8s?

I want to buy 10 iphone 8s for my family and is there a way to bypass the two er box.
Ca someone also fully explain what is meant by per box

Per box, basically 2 per 1 person ordering.

I had a friend order 1 for me a time (& ordered 1 for himself) & they both came in 1 box*

*they usually come in a nondescript box & that contains the actual phone box(es)
