I've noticed today that when you use certain postcodes, the messages that come back are different. Rather than saying "we're on our way" it comes back with a message saying how they haven't decided where they are going yet and to register your interest?

It also tells you in the corner how much interest they have had from the area in question, and for some reason depending on area it's colour coded. Orange shows up in certain places, and I've seen a dark blue as well.
