Dear Mr John:
Subject:1000T 铝滔卷(这个自己翻译）
Received your letter dated 12/18.We're regret to know that our quotation is high.
We've contacted with our manufacter.We have to point out that for the power shortage and materials rise,we can't maintain the present price,not to mention depreciate.
As our products sell very well,you can make extra benifit from the price rise if you accept our offer.
Waiting for your good news.
