Just had 24 hours of frustration with Amazon, an unusual event. I attempted to use two $25 giftcards to get the new Citizen Kane BD set free. The first gift card worked fine, the second gave me a string of different error codes culminating in one saying it had already been redeemed. I knew this wasn't the case and got a totally brain dead CS person who didn't even know about the Amazon Rewards Visa and the gift certificates they send. So after 24 hours and several phone calls/emails, I get this perfunctory answer saying it had already been redeemed, and they gave me the email address that had redeemed it. Not my email address. Just called and raised holy hell with them and they credited the order $25. I am now researching the "phantom" email address. It is an interesting email address--it is the plural surname of a famous mystery writer with the AOL domain.
