Dear David,
I’m writing to you to introduce a website whose service is about used goods exchange.
The website is established by my good friend, who wants to help people make full use of items, unused for a certain length of time. My friend mentioned that what is currently needed most by some people is original English-written magazines or other reading materials. If you have some and no desire to preserve, would you like to exchange for something of a Chinese style. Additionally, it’s a good idea that you call on people around to join us.
I’m looking forward to your reply.
