I live in Italy, want a new iMac, and am not willing to spend 600 USD more here than it costs in the US. This summer I will visit the US, and would like to buy a 27" model. The box is quite large, I want to put it in the checked luggage. Is this crazy? Am I required to pay customs tax on it? In the end I will move back to the US so maybe I can talk my way out of paying the import duty. Any advice is appreciated. Thanks!
