Great question! KDP author copy shipping details can definitely be confusing. Yes, Amazon does have package weight limits, and larger orders may be split into multiple boxes depending on the total weight, book size, and shipping requirements. The exact number of boxes will vary based on the trim size, paper type, and page count of the book. For a 200-page book, 100 copies could potentially be split into multiple boxes, but the best way to know the exact shipping cost and packaging is to add the quantity to your KDP order page before checkout. Amazon will calculate the shipping based on your specific book specifications and location. It’s also worth remembering that author copies are printed at your print cost (not the retail price), so it’s a great option for events, direct sales, and local opportunities. Hopefully some authors here who regularly order bulk copies can share their experiences as well!
