Hi Mostyne.
Thanks for that, it seems to confirm what I was saying, ive just checked our bill for this year and it is 51.05 but it also apears they can charge you for your wife as he was saying.
Weve had our PO Box six years and only had one price, what I cant understand is why we have not heard of anyone else  being notified of this enforcement in other areas.
