This is very common in countries like Brazil that have extremely high tariffs. People fly to Miami to buy a MacBook and iPhone and take it back in their luggage because even with the cost of the flight and hotel, it's cheaper than buying it locally. Just get rid of the packaging and put some apps and files on them so they don't look new.
