THANK YOU AMAZON FOR THIS FEATURE THAT I JUST DISCOVERED!  I love it!
I love that I can use this to load all of the partial balances that I have left on prepaid gift or credit cards.  So many people give these for gifts and then when the balance gets low on them, there isn't anywhere you can use that last amount!  NOW AMAZON HAS SOLVED THAT PROBLEM!  I have loaded all those old cards (around 15 of them) to an Amazon gift card (the lowest card balance was $1.68) and I have MONEY TO SPEND that was just going to waste.  I have gone crazy ordering stuff this week with this new found money and the gift card is so easy to use.  It defaults to use this card balance first (which is a combination of all of the old individual card balances)!  That is so easy to use.
