We must stress that this departure from our usual practice relates to this transaction only.We cannot regard it as setting a precedent for future transactions.

我能看懂些,不要翻译工具翻的,翻出来都不通,
1楼的明显翻译机，自己读读通不？

亲爱的Smith先生：
感谢你2月10号来函订购5000打衬衫.（1打12个）
我们考虑了你关于用一个30日信用证付款的提议.通常我们不接受有时限的信用证.然而,为了我们两方今后长远和更多的利益关系,我们决定破例一次.
必须强调的是,这种破例做法仅限于此次交易.在今后的交易中,我们还是不能接受这种信用证.
附上针对此次订单的销售合同,第TL120号.如果您能够遵循程序我们将万分感激.
Yours faithfully,
Enc.
