Dear xxx,
I am glad to hear from you， and much concerned about your requirement in the letter.

Regarding our last quotation¹, you consider the price to be high for you. I do think it is the common issue we face currently. As you know, the price of raw material goes up beyond our predict. We are proceeding² to improve craft to lower the cost effectively.

The market goes big for these products day by day. Most clients have urged us to complete their orders in spite of high price. They all agree that these products are of most potential high profits in the near future.

Provided we offer 30% discount to you, could you like to double your volume? If not, I would like to kick off 10% price to start an initial friendly cooperation between us.

Your further comment is highly appreciated.

Yours truly,

William
