感谢你方寄来的电冰箱报价函。然而，我们却发现，你方所报的价格在此地没有足够的竞争力来找到销路。我们建议你方将价格降低10%，这样，我们将乐于订购200台。如你方同意我们的建议，请来函告知。

Thanks a lot for the fridge price quotation sent by you.

Nevertheless, we found that there was no market here for such a price without enough competitive power.

Thus we advise you to cut down 10% of the price, so that we will be very pleased to order you 200 fridges.

And if you agree, inform us by mail please.
