Dear Sir or Madam,
Thank you for letter of 5 May 20xx.
I must apologies for the delay in replying to your letter of 15 April. Unfortunately some members of our staff have recently been off sick. This, at a time when several of our employees take their annual leave, has resulted in unavoidable delays in replying to letters.
I enclose the price list of our company as requested and look forward to hearing from you.
Your sincerely
邀请您20xx年5月5日的来信。
我必须为延迟回复您4月15日的来信而表示歉意。
不幸的是我们一部分员工最近生病，而与此同时一部分员工正在休年假，这一切导致了不可避免地延误回复您的来信。
我随此信附上您索要的我们公司的价目表。
期望您的来函。
