gift card
I got this from my son for Christmas so I could order books, etc. for my new Kindle Fire (which is awesome, by the way).  I think this was so incredibly thoughtful of him.  The only complaint/warning I have is that you have to set up one-click purchasing to order things from the Kindle.  The only problem I have with this is that one-click doesn't give you the option to use another form of payment.  I solved this by using the gift card for one-click purchases for books, but order other things from my laptop where I get the choice at check-out to use another payment method so that I don't use up my gift buying gifts for others (sounds a little selfish when I actually write that).  I guess this adds another level of protection in case I lose the Kindle or it gets stolen since they could only use it to buy stuff up to the amount left on the gift card.
