问题：今天写了一封邮件给客户：表达知道美国疫情严重，我们可以提供口罩，客户需 不需要口罩，如果需要，请提供私人住宅地址来接受口罩。之前催确认PI一直不回复，这次回 复我了，并且再和我讲价，说从中国来的病毒疫情期，现在从中国买，冒着风险，你们没有 折扣吗？我应该怎么回复呢？我是不想给折扣的。
Thank you very much for your kind reply.
Do you believe I already gave you the discount without reducing the prices?
Due to the Outbreak, we have to suffer a lot from it, especially the increasing the material cost. Now we have to pay at least 3-5% more for the material, anyway as a professional and responsible sales, I still keep my promise to give you the same price.
All the time I have a doubt that why our raw material could rise the cost so easily and confidently, but
when we face our customers, it is so difficult for us to mention anything about the increasing cost, aha. So I really hope you can share your best understanding and keep supporting me,your supporting during the Outbreak, sure I will feedback you more in the future.

Looking forward to your kind reply.
