今天早上打开邮箱的时候看了下客户发来的邮件，是关于塑料阀门的。他说欧洲那里的价格只有我们价格的25%，我想这个应该不太可能。

客户的邮件如下：Hallo Belinda,

                       Thank you very much for the information, unfortunately your unit prices are to expensive for us to continue with this enquiry, we can purchase this type of valve in Europe (no import charges) for around 25% of the your quoted unit cost. If you think you can supply at around this cost then you may reply, if not then no further communication is required and I thank you for all your help.

Regards

Tony Dale

我觉得这个客户是有意向购买的。各位易友，该怎么回复比较好呢?
