越南客户要求和其他客户一样价格，要怎么回复好？

我们公司是工程机械配件，越南市场的挺好的，有一两大客户，但是价格也是有给他们优惠，现在在一个新客户，说是要得到相同的价格，要怎么回复他好呢！附上邮件，请各位达人给点意见！这个客户量也可以，接近两个柜，发展潜力还是有的，也算挺大的，但是第一次合作，也不能给他太低的价格！ Tks for contact me. I'm little busy in these days. I'm interested in doing business with you. But considering your quotation i wonder that may it is a little higher some other Vietnamese companies buying from you or not. because with this quotation we he to sale out higher than them though we try to keep minimum profit. Pls consider this competitive market. I'm ready to compete fairly with all others but we need fairly prices import too. Actually we don't always pursue the too low price policy, but we need the same product, same prices. Can you explain or consider the better prices for us? 要怎么回复好呢？谢谢
