Yes, I've had that card problem happen to me too. In fact, I just sent a card to someone that was never received.
I have no idea why they dont go through. My guess would be either its the site--in my case I had never used that one before--or possibly my firewall on my computer blocked it....but I would think that I would get a message from my firewall saying so.
danstigerangel, Email me with your SS's name and Ill see if we can work something out.
