I called the regular ressie number today (407-934-7639) and asked if there was a code attached to me. The CM was very nice; said no, but they are always sending them out so stay on the look out.
I also changed my ressie from PC to CBR so I didn't feel like I was calling just to ask about the code but also to upgrade.
I'll stay on the look out since I see some others in my area have gotten their postcard, but not me
