I scanned the code and it didn't take me to a website, was a bit annoyed that it didn't work. If you go to the website that's on the card it works and you can add the code. The contest expiration date on the card is for this past August, so I'm amazed that this is what happened since they obviously should have gone out a long time ago.
Hopefully someone here finds out when they come back so we don't miss out on them, otherwise I guess I'll be happy with the 2 I got.
