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：
茲證實我們雙方關於煙火和蚊香的往來電報。我們很高興在價格方面達成了協議。你在上一封電報裡通知我們，只能報五百打煙火和三百箱蚊香，這個數量是不夠的。由於中國商品質量好，我們越來越多的客戶喜歡購買它。如我們不能充分供應市場，他們勢必會從別處購買。因此，我們希望你至少能報一千打煙火和五百箱蚊香。
我們感謝你方的努力和合作，相信這次訂貨將會帶來今後更多的交易。
盼早復。
