Thank you for your letter and sample of April 15.
As you konw ,we are very satisfied with the sample tests. but your price is considerably above our usual figures and it's over the market price already.Based on available information, the brand you have offerd can be obtained from other places.The price is much lower than yours.We cannot deny that your product's quality is better than others,however, whatever the case may be,the gap between your price and ours should not be too great.To have this business concluded, you need to lower your price at least by 5 percent, we believe.
We need to point out that this is the best we can do and we hope the revised quotation would allow you to place an order with us at an early date.
Your Sincerely
希望可以幫到妳
