扩充工厂、开立分店、顾客增加、扩张门市等，都是扩大交易的绝佳机会。逢此机会时，可以应用这封信。

Dear Sirs,

We are pleased to inform you that we have now enlarged our business machines department and are considering the addition of new lines to our stock.

Your various typewriters and calculators would fit in well.

Please send a complete range of catalogs and samples which are in production. We expect you to quote your lowest prices and would like to know whether you can supply from stock.

If we decide to put your goods into the market we want your assurance that you will not sell them to other firms in Taipet.

We look forward to your early reply.

Yours faithfully,

敬启者

很高兴通知您，本公司现在扩充事务机器部门，并考虑增加新的库存货品。

若我方决定将贵产品引进市场，希望贵公司保证，不将产品销售给台北的其他公司。
