As far as I'm aware Royal Mail is a fixed fee Peter..
Somewhere every day there are tougher than we endure taxes and impositions its called user pay system as you said recently Peter its great to pay your way in your own country. All the best everyone as a retiree on the full pension for most of twenty years it gets exciting, as I read the forum if any one of us kept accurate records of how much we spend on our gear and the results the cost per pen is horrendous.
Take care out there. Peter.
I do think that paying the correct amount of taxes is right, although when I see MPs fiddling expenses with impunity my instinct is not to condemn those who do not pay their dues, but if everyone did that we would be in the same hole as Greece.
