开发维护篇（14）：维护老客户
Dear Mr. Reeves,
亲爱的李维先生：
We are most gratified that you have, for several years, included a selection of our products in your order catalogues.
鉴于贵公司的订货目录多年来收录本公司产品，特此致上深切谢意。
We are pleased to inform you our latest product is available now. The new machine vastly excels the old one in performance. If you, our old customer, are interested in it, we can offer you a 10% discount.
我们很高兴告知您，我们现在有最新产品上市了。新机器在性能上大大超越旧的。如果您对它感兴趣，我们可以给老客户九折优待。
Looking forward to hearing from you.
期待您的回复！
Yours sincerely,
Kevin Smith
