May we explain the increase in the prices to you. They result from three points: the sudden rise in freight cost on September 19 because of tighter freight and port market; the continual increase in the prices of material; the steady rise in the labor cost as the result of economics in the directions. We know frequent changes of price are most unfavourable, but we can’t keep our old priced any longer to cover the increasing cost: cut the allowance to 3% on purchase quantity not less than 1000 articles, and reduce the commission to 4% each.

尽管我们感谢你方4月2日来信，但很遗憾，即使你货物式样新颖，工艺精良，其价格也不与市价相称。供你方参考，在该市场上，相同质量产品的价格又下降了10%。为了你方利益，请减价20%以与低售价相称。
