Does work. Make sure you use the "pin" and not the card number when redeeming it. Netflix will not recognize the card number. I did get a bit of a scare on the redeeming. I entered the pin and a pop up asked for my zipcode. I entered that and hit enter and I was given the message that the card had already been used. I was about to contact Amazon, but thought to refresh the account page first. When I refreshed, Netflix showed that I had a credit minus the first service payment. So the gift amount did apply even though it said the card was already used. Weird glitch, but I'm happy in the end that the gift balance applied. This is more convenient than buying an actual gift card from a store. I don't like having a credit card on file with Netflix.
