If I purchase the print book but also want the eBook and other digital files (videos, practice files, etc.), do I need to buy both of them (digital version here, and print version)?

Yes. The print book and digital files are sold separately and digital files do not come included with your print book purchase. However, if there are any practice files associated with the book, those will be included with your print book purchase. More information on that will be available within the pages of your print book.
