If the breeder checked out, I would just be patient, and maybe send him an email to keep you updates, and expressing your concern. He might just have a long drive to Delta or something, so he might be trying to see if he will have any other orders to ship this week, so he can do it all in one trip. As lond as he's keeping in contact, and too much time hasn't passed, I'd give it a few days before getting too worried.
