La Nación uncovers numbers and items that have been confiscated by AFIP at the Ezeiza Intl. Airport.
However, it fails to provide the basis of these confiscation: in the comments, readers are speculating that those confiscated items were obviously being brought in the country for resale, whereas from my understanding of the AFIP slip of paper handed on the place, the 300 USD limit includes personal items, as well.
