Thanks Ila for the tip.I had the PO box arranged by the Royal Mail(UK) for some time but I had problems with them.The messed up with one delivery at the local depot and the package was sent straight to my home address(this is not a joke) and I was lucky that I was on my own that day,otherwise you can imagine what would happen if my"better half" was at home.Anyway,I decided to cancel the agreement after 6 months as I wanted to avoid any further cockups.So I'm afraid this not a solution for me but again,thanks for your advice
