Why is there no option to create cards in the iPhoto app? It seems odd that they have options for photo book but no cards??

I just purchased the iPhoto app for the ipad. I was very disappointed that there is no place to create cards/post cards from the iPad itself. It really seems odd since they have options to make photo books but nothing for cards and prints?

Is there any other thing I can use to get this feature from the ipad itself?
