We understand that you are one of the largest manufactures of handmade art and craft products in your country, and we want to avail this opportunity to express our hope of establishment of business relations with you. We are the leading dealer in art and craft products in this district where Chinese handmade art and craft items are especially popular. Will you please send us a copy of your catalogue and current price list for your art and craft products? We have recently received many inquires from our retailing shops about the said items. We are sure there would be brisk demands on our side. If the quality of your products is satisfactory and the prices are reasonable, we will place regular orders for considerably large numbers. We would like to know whether you are able to allow us a special discount, say 6%. This would enable us to maintain the favorable selling prices in this area. We are looking forward to hearing from you in the near future. Yours sincerely, How did the addresser(写信人) know the addressee's(收信人) name? From______.
