１０％OFFと送料無料は大変嬉しいです。
しかし、日本に入国する時に関税と消費税がかかります。
初めてのお取引で申し訳ありませんが
もう少し値引きは可能でしょうか？
無理なお願いをして申し訳ありません。
ご検討お願いします。
I am so glad that 10 percent discount and free charge of the shipment.
However, the customs and consumption tax will be charged when getting into Japan.
I am sorry for asking you although this is the first dealing, but could you discount a little more?
I am very sorry for asking you too much.
Thank you very much for understanding and consideration in advance.
