A:Answer If you are referring to Best Buy sending this or any other item to anywhere other than the 50 States and its possessions, then the answer is "no" per the following page from their website: http://www.bestbuy.com/site/Help-Topics/International-Orders/pcmcat204400050019.c?id=pcmcat204400050019
If, on the other hand, you are asking whether an individual who purchases this or any other item is allowed to ship from the USA to overseas, then the answer is "yes," but, it is expensive: USPS Priority Mail Large Box flat rate to Turkey is $90; USPS Global Express for a large box would be about $270. https://ircalc.usps.com/
If you travel overseas, make sure to bring your receipt, regardless of your destination. If you intend to return to the USA with that same computer (or any other recently purchased device or object), make sure to request Form 4457 from Customs at the airport/station BEFORE you leave the USA, or you might be charged duty upon return to the USA!
