Our upgrade offer to get 40% off the print and 50% off the ebook of a new edition of a book unfortunately wouldn't apply to your suggestion. Windows 8.1 Inside Out is a completely new book, and not just a new edition of Windows 8 Inside Out.
I will send you a limited use discount code that you can use if you would like to purchase Windows 8.1 Inside Out. Have a great day!
