Let me confirm something.

You ship a box which include only a pair of boots, right ?

The additional is 6 pair of boots, so I have to pay $360 ($60×6) is what I understand, is it correct ? then payment should be done via Paypal ?

確認したいのですが、出荷は一箱に一足を入れての出荷ですよね?

追加は6足分ですので $60×6=$360

をPayPal で支払えばいいですか?
