I downloaded the Cards app the day it came out and sent one to my girlfriend just to see what the final product would look like. This past Monday, I got a notification from the Cards app that my card had been delivered to my local post office and it should come in the mail that day. It's now Friday, over a full week from when I submitted my card order and it still hasn't come in the mail. Has anyone else used this app yet? Has your card been delivered yet?
