Best way to ship to Italy?
You just dont.
Hate to say it but your just asking for trouble when you ship out of your country. I know your wanting to help and make a sale but most of the time its more hassle then its worth IMO.
If it gets lost or take a long time the other party starts screaming troll at you and just starts all kinds of hell. I did it one time, and will never do it again. Took almost 4 weeks to get there and after a week they were demanding money back and oh how I took them because they lived in another country, and all kinds of other BS, when it finally showed up and they say the date it shipped all I got was "Im sorry". For me that one time was enough to say the hell with it no matter what it doesnt leave the US.
