Patrick you are so right... When I was "visiting" these countries I did not hesitate to carry things home - or "ship" that special purchase.
But now living on the economy in Italy, it's a different perspective! Mailing home "standard" items to my kids has become an "event" due to costs. Good news - We are paid in Euros which is a blessing now!!
We do travel to other countries from Italy, especially by plane. On the low-cost European Airlines you have to pay a premium for luggage - number of pieces AND weight. So we pay that price to "carry back" wine, souvenirs, and gifts.
Indirectly it's the same - we carry rather than ship... But that being said, I just would not trust anything I valued to the Italian Post Office.
Be it Murano glass, wine, pottery, etc., I would first work through the vendor before considering other "mailing" options!
Have a great time Tennille; Wish I could get my wife to backpack Europe!!!
Ciao,
Ron
