Passports

We have a passport updating situation here - mine is out of date and our daughter has never had one so I've been trying out the on-line application service.  It seems to work quite well, all our data has gone in and so far I've not had any questions raised about it so now we will see what arrives in the post for us to check and return.  Amazing how many companies have sprung up who will 'help you' apply - at a cost.  I wonder how much business they get?  it really wasn't that difficult to fill in!
