A business opp. for someone with an empty suitcase.
I'm sure most of us would bring you over a 15kg suitcase (or 20kg on some flights) for say £40 towards the price of the flight + if you gave us the prices on that website everyone would be VERY happy!
No parcels going astray (unless the luggage does) in the post office + no import duties - would there be any?
We might even take advantage when we finally get out there for good - when the cravings start!
