Your right it is expensive and the amount you gotta pay for your wife and son makes a big differnce if you send postal. So i cant blame you doing it that way.
good to know about how the form is devided and like you i would have printed duplex.
something as simple as adding a blank page probably took months to achieve and yet anybody with a pdf editor could add a blank page in seconds to the file grr.
better start printing out that form now and going though the huge object that is the missus visa evidence and info file that should keep me busy for the rest of the day
