Ben's right. Anything mac: a new macbook pro, ipod, iphone, ipad, cables, spare parts, etc. There's a lot of people here (both foreign and domestic) having a hard time getting this stuff because of the import controls. I waited 5 months for a replacement HD. Finally ended up buying one in NY.
But would a tourist bringing in a brand new MB Pro Retina, in the box, raise any eyebrows at Ezeiza?
