1, we have received your 2007 9.13 Chinese green tea on offer letter, thank you for your offer.2, the price you quoted is that we have received, we can not but express regret can not写不下了

Dear sirs, Thank you for your counter offer of September 13,2007 for Chinese green tea. We regret we find it difficult to comply with your request of reducing the price by 10%. Our price is resonable and it will be unprofitable for us if we cut it by 10%. So we hope you will give a second thought to it and have this business concluded on the basis of mutual benefits. Yours faithfully,
