英语翻译先生您好!我己经很清楚的告诉您了,SDY公司经营的原则是不承担样品邮寄费的.这次我们给你寄样品的邮寄费是$70,如果你愿意不承担,那我们就不能寄样品给你.另外你下订单我们确认后,你要按订单上的货款的总额予付30%订金给SDY公司,余额的70%货款按发货期计算50天内支付.SDY公司是讲诚信的,如果你不能这样做,我们的合作将无法的再进行下去了.请大侠翻译.有+分.小弟在这里先谢谢了.

Dear Sir,
I have clearly informed you that SDY would not bear the postage of samples which was one of the company's regulation.
这次我们给你寄样品的邮寄费是$70,如果你愿意不承担,那我们就不能寄样品给你.
It will cost us USD70 to send the samples to you this time,if you are not willing to bear the expense,I'm afraid we can't send the samples to you.
另外你下订单我们确认后,你要按订单上的货款的总额予付30%订金给SDY公司,余额的70%货款按发货期计算50天内支付.
Btw,after we confirm with your order,you shall make the down payment to SDY,which is 30% of the total price in your order.And the balance,70% of the total price,shall be paid within 50 days after consignment.
SDY公司是讲诚信的,如果你不能这样做,我们的合作将无法的再进行下去了.
SDY is a very sincere company.If you can't do what we mentioned above,then I'm afraid we can't go further on our business.
