We purchased last June and I have already forgotten the time line, however I know that I had a temporary card which much have come with the original papers as we used that for discounts while we were on vacation. Then I beleive after we closed and received our closing documents we received our actual plastic cards.
Sorry that I am a little fuzzy with the details. I am sure someone will be more exact.
I have also read that you can go to SSR and have one printed up there as well.
