I would recommend contacting our customer service team who can set you up with an order for the 10 Ebooks. Just so you know, when you purchase an Ebook, you get access to all the formats, not just the PDF.
You can contact us at:
1-707-827-7019 (outside the USA)
7:30 am to 5:00 PST
Or, email email@example.com so that we can get you set up with an order.
Customer Service Rep,
