若产品更新换代，或者新产品一上市，需要第一时间通知老客户，以便有缓冲时间来开发，或者及时调整市场策略。一旦信息延迟或滞后，让客户没有及时做好准备；一旦新产品冲击他的本土市场，而他原有的库存压力较大，这都容易让他在资金和销售上出现问题，处于被动的境地。

Sorry to trouble you at the moment. I would like to check with you about your last order for 56 pcs CRV screwdriver bits kit. Have you sold them out?
Now we developed a similar set，and used carbon steel，instead.The pricing could be roughly 30% lower.We plan to do a promotion in Holland this June. Do you have interest in this set?
Best regards ,
Tony
