great for eCards
Got a couple of those electronic gift cards (MC, VISA) that are such a pain to use on-line.  The easy solution; load them as a new credit card on your account then reload your Amazon GC balance in the exact amount of the electronic credit card.  After the transaction clears you then delete the CCs from your account.  Now you don't have to worry about split transactions, leftover amounts on the credit card, etc.
