My daughter will be turning 18 while we are on our NYC holiday. We are keen to get her a Samsung Galaxy S4 and wondered if it may be cheaper to buy it in NYC than purchase it before we leave Aus. I believe we would be paying around $799 here (unlocked). I've heard that the Best Buy store in NYC now has a Samsung section and was wondering if any of the locals, or Aussies, would have any idea of how the prices compare to here? Also, are they available duty free from anywhere?
