【正确答案】正确答案： Dear Sir or Madam, I really need your help with this. I have been buying books from Delta for nearly 8 years, but recently the books sent to me were either delayed or damaged. As one of your reliable buyers, I am terribly disappointed. Here are my two suggestions. More options for express delivery should be offered, that is, we customers can choose the most suitable delivery method ourselves. Sometimes, what we care more is not the fees charged but the time taken. Another suggestion is that you take more effective ways to protect your products, such as filling more sponge in the gaps and using harder wrappers. I"d be more than grateful if those unhappy experiences would never happen again. I greatly appreciate your help. Yours faithfully, Li Ming
