3、
2月15日来函及所附花式样和价目单均收到，非常感谢。我们选了三种，现随函附寄第777号订单。货急用，请即装。

定单第777号
Abc有限公司
伦敦，英国
敬启者:
请供：
数量 货号 单价 交货期
250打 3456 每打2美元 8月份
160打 7890 每打4美元 8月份
90打 2134 每打6美元 8月份
包装：每打装一内衬锡纸纸盒，每120纸盒装一木箱。
保险：按发票金额高百分之十投保水渍险。
唛头: 与我方以前定货相同。
付款：不可撤销信用证凭即期汇票付款。
我们已经通知我方银行按本定单金额开立信用证，不久你方可收到你方银行的通知。

4、事由: 你方第456号定单
我们已接到你方4月15日来信。要求我们对第456号定单接受“付款交单”方式支付。

正如在谈判时我们已经约定的，货款必须以保兑的，不可撤销的、凭即期汇票支付的信用证付款，因此我方难以接受你方这一要求。但鉴于你我双方之间的友好关系，我们破例同意接受60天期的即期信用证。我们相信这一特别照顾定会使我方将来得到你方更多的订单。
等候你方的信用证，收到后我方将立即安排装运不误。
×××谨上
