Very easy to use
This is the best idea on Amazon, when you are left with giftcards that have a dollar or even a couple of cents load them into an amazon gift card. You would be amazed how much you would get from just gathering the ones you thought you would never be able to use.  I ended up with 10 dollars from all the left over gift cards I had at that time.  Happy with it.
