We are told that you are head of your school. I am writing to you because we have a new type of recorder for sale and wonder if you would like to buy it.
The model is AW----501 and it was produced only one year ago. We would be happy to sell it to you for 560 yuan. That is the cheapest one of the same kind on sale.
If you are interested in it, please write to me at the above address. Could you suggest a time when it would suit you to visit us and try out the machine?
I look forward to hearing from you.
