怎样表达在涨价前订货？

 　　Thank you for your letter of October 10 for business copiers. We are now sending you our pricelist and catalog of the newest types that are under production and we can supply at once from stock.

　　We want to notice you that prices of copier parts and components¹ have gone up steadily² since the second half of the year. Though we have tried hard to keep our quotations³ down, we are afraid the margin⁴ for keeping on going like this will not long. Therefore, we suggest that you will let us have your order before further rises in costs, which will lead to a raise in prices very soon unavoidably.

　　感谢贵方10月10日关于商用复印机的询函。现随函奉送本公司正在生产的、并有现货供应的最新型号的产品清单和价目表。

　　我方想告诉贵方，自下半年以来，复印机的零、部件价格一直不断增长。尽管我方尽量压低报价，但恐怕有此余地的时间不会太久。因此，建议贵方在零、部件再次涨价，并不可避免地引起成品涨价之前便向我方订货。
