ありがとうございます。実は、このメールの前にもうひとつメールが届いていて、そこには 「We have debited a small amount to your credit card. As fraud prevention, we need you to call your bank or credit card company and find out how much we have debited (in US dollars) and what date it was done.Itusually takes 2-3 business days for the charge to be posted to your account.Once you email us with the exact dollar amount and date of the charge, we can release your order for immediate shipment.We can not release your order without this information. 」と書かれていました。ちなみに、６万円ほどの買い物をしたのですが、クレジット会社からは１８０円引き落とされています。
