I attempted to register my DotNetNuke Module Programming (ISBN 978-0-470-17116-5) and DotNetNuke Skinning and Design (ISBN 978-0-470-10963-2), but I got an error stating that "The following identifiers match no registrable product." Is there any way to register my print books so that I can upgrade them to ebooks?
Thanks in advance for your response
I apologize for the frustration of not being able to register those books in your account. At present, if we do not sell the print book of the title it is not eligible for the $4.99 eBook upgrade. There are discounts you can use to get those eBooks for less than the cover price which you can find here: https://members.oreilly.com/account/b...
