My father-in-law exceeded his 5Gb free iCloud drive and asked me to drop by and show him how to do the purchase. He doesn't have a Mac, but has an iPhone and iPad.
Interestingly, after getting as far as Buy Now on both devices, the whole process resets and we kept getting prompted to log in again. After 3-4 tries, I looked at my notes and saw that iCloud For PC (?) can also be used. That process worked fine, first attempt...even with the multi-factor authentication involving concatenating the Apple password with the security code (sent to the IOS devices).
Pretty bad that we could only make it work on a PC.
