元の翻訳 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.
