In your letter of December 31, 2017, we got your enclosed price list and catalogue; we found that one of your goods is to our satisfaction, so we are now post its picture back to you. Would you please inform us in detail its price, terms of payment and terms of shipment? We hope you would quote us the most reasonable price. As we have a large population here, if the goods are sold well, we are sure to place regular orders with you.
