If sending goods to Italy I would strongly advise sellers not to use Posta Italia. For your own sanity - they really are a poor transporter, lazy, and could not care. They are paid, delivery is an option that seldom happens.
Goods returned stating address could not be found. Remembering that Italy is an old country these lies fall short. Shoddy workers, untrustworthy and should be replaced by decent foreign workers. But Posta Italia is very bad news to seller and buyer alike
