Great Idea.  5 Stars.
This is a great idea which Amazon.com has started.  Being able to have gift cards on hand for that last minute gift.  These are so easy to use.  Go to the website listed on the back, add any amount from 50 cents up to $2000, remove the sticker from the front of the card and as soon as you receive an email from Amazon.com you have an instant gift.  Very simple and everyone loves to receive Amazon gift cards.  I have a few of these always around just in case they are needed.  No need to stop at the local retail store to purchase the card because you can have them on handy for any occasion.
