OH NO!!! I received a christmas card from Miss Meow and I also received your card!! So I just put "please forward" on the envelope and sent it off to you!! I hope you get it! I don't even know where they will return it to if not...me or Miss Meow in Austrailia!!
If I get it back I will send it off again to the right place!

Edit: I just spoke to a co-worker that works a part-time job at the post office and she said that chances are the post office will deliver the mail even with the incorrect zip code as long as the rest of the address is correct. So you should get the card.
