Christmas gift issue solved!
For Christmas, I used the cards for my nephews, nieces, and their children ranging from 15-24 y.o.. Trying to buy for boys/girls with a broad age range poses a challenge. They are all computer savvy and a cash Amazon card addressed all  the gift issues in a equal and flexible manner. An obvious, yet useful, additional advantage is the portability and no wrapping necessary. And selfishly, the quick turnaround from an online purchase to home delivery, spared me a lot of time and worry.
