Dear XXX,
Our company has recieved the order #356 on May 6th. The order contains 500 billiard tables. The cost is $600 for each table including shipping and the insurance from China to LA. So the price is $300,000 in total. Your order will be delivered in August. You can pay by any credit card with sight draft payment. Once this order is confirmed, it is irrepealable.Thank you.
一般美国结算时要把总金额写上,我已经在文中加进去了.我在美国网购时注意了一些专业用语,这篇信函比较正规了,美国买家肯定看得懂.
