You are the manager of Simpsons Hardware Store and have received the following handwritten letter from a man who lives in a small town 165 miles away: Dear Simpsons Hardware: I own a Simpson Model S4320 grass trimmer and had it for over 15 years. The gas cap begun to leek last week and I need another gas cap for it. I know your products have a lifetime warranty so please send me a new cap as soon as possible. Thank you. Frank Dunford Box 26 Emmetsburg, Iowa 50536 Mr. Dunford is not in your database, and you are not sure he has ever been in your store. You must now write a reply letter to Mr. Dunford and tell him that only Simpson "tools" have a lifetime-replacement policyother products do not. His string trimmer had a one-year warranty. Because his trimmer is so old, you do not carry parts for it anymore; however, you can order the part from another supplier at a cost of $17.65, plus $5.00 shipping and handling. If he will send you a $22.65 check, you will order the part and have it delivered to his home. Delivery time will be about three to four weeks. If Mr. Dunford decides to buy a new trimmer, he can look at new models on your website (gosimpsons.com) and order one online but you do not know if he has a computer. Apply the principles you learned in chapters 2 and 3 of Writing and Speaking for Business.
