A specimen Letter
Dear Sirs:
We 3 email exchanged between us regarding fireworks and mosquito-repellent incense and are glad that we have come to an agreement on the price. Your last email 3ed us that you could offer us 500 units of a dozen fireworks and 300 cartons of mosquito-repellent incense, which we think is not enough. More and more clients in our country like to buy Chinese products because of their good quality. If we do not take care of the supply of our market, they will naturally turn somewhere else for their needs. So we do hope you can offer us at least 1,000 units of a dozen fireworks and 500 cartons of mosquito-repellent incense.
We appreciate your efforts and cooperation and believe this order will lead to considerable business in the future.
We look forward to your early reply.
……Import Corp.
先生：
兹证实我们双方关于烟火和蚊香的往来电报。我们很高兴在价格方面达成了协议。你在上一封电报里通知我们，只能报五百打烟火和三百箱蚊香，这个数量是不够的。由于中国商品质量好，我们越来越多的客户喜欢购买它。如我们不能充分供应市场，他们势必会从别处购买。因此，我们希望你至少能报一千打烟火和五百箱蚊香。
我们感谢你方的努力和合作，相信这次订货将会带来今后更多的交易。
盼早复。
