When Dr. Bellows rings the doorbell, Tony is in his full uniform. He goes to the door, there's a cut to a closeup of Jeannie in a pencil cup, and cut back to the door as Tony answers it...but without his coat.
When Jeannie turns the publisher's letter into an advertising mailer, it reads, "Robinson's 83rd Anniversary Sale." J.W, Robinson's was a chain of department stores in the Los Angeles area. Locations on the flyer include Los Angeles, Beverly Hills, Pasadena, Panorama City, and Anaheim. The chain later merged with The May Company and today, they are part of Macy's. The prop department used a real flyer rather than printing one up with Cocoa Beach on it.
