iPhoto book: "This Apple ID cannot be used for 1-click ordering" despite it being enabled in my profile.
I am trying to purchase an iPhoto book that I created. I keep getting the error message "This Apple ID cannot be used for 1-Click ordering.", despite having the express checkout enabled on my Apple ID. I created a new Apple ID, but had the same problem. I also used my husband's Apple ID with the express checkout enabled and always get the same error message. I don't know why I continue to get this error and am not able to purchase my book.
MacBook Air, OS X Mavericks (10.9.5)
