These are MARVELOUS!!  (once you know how to scan the QR code!)
I will ALWAYS have a pack of these on hand!  It is completely worth the $2.99 for a 10 pack!  That is $0.30 per card to have it readily available in a nice gifting sleeve and the ability to load with the amount you choose, whenever it's needed.<br />That being said, I understand why some have complained about the activation process with the Amazon App.  To make it work, I had to download a QR scanner separate from the Amazon app.  Then when I scanned the QR code on the back of the card, it opens a link in a web browser page, and I can complete the gift card loading process that way.  It's easy-peasy to load and only takes a couple of minutes, but it may require a separate app.<br /><br />I agree that Amazon really should get the QR scanner working for these gift cards within their app.  I'm giving them 4 stars just due to the inconvenience of the Amazon App not working to activate them, and if they correct that problem I will change my review to 5 stars.
