Query: Defective books

I originally gave this 5 stars for the price, in spite of the cheap cardboard trunk, but due to the publisher's and Amazon's poor quality control, I must give this a lower rating. Book 4 has a section of duplicate pages where missing pages should be, and Book 7 has creased pages with blurred print. Amazon will not replace individual books within the set, so I must take all 18 lbs to UPS and make arrangements to be home for another UPS delivery.
