Sir/Madam, Good day! I am Sir Joe and I am interested in ordering some of your products for my company. I will like you to send me free samples for testing before i make any order. That is my company’s policy. I will show it to my customers and also my staffs for them to see how quality your product is. Kindly get back to me if you agree to give me the free samples. I look to do business with you soon. Thank you. A. 垃圾类型 B. 无明确目标型 C. 潜在客户型 D. 明确目标型
