P.S....a quick goggle yielded this:
Entrance Regulations
All travelers entering Argentina must fill out a customs declaration form. The country has different rules for different travelers: citizens and residents entering Argentina from a bordering country after less than a year away may bring in used personal items, including household goods, and up to $100 worth of cigarettes, cigars, alcohol and food. Argentine citizens or residents returning from any other country, as well as visitors from non-bordering countries, are allowed to bring in $300 worth of the same items. Visitors traveling with pets must have a veterinary certificate of good health provided by an Argentine consulate. New items and gifts are subject to heavy taxation. Amounts of cash totaling more than $10,000 must be declared. Prohibited items include narcotics, explosives, unauthorized firearms, anything intended for commercial or industrial use, anything banned for public, animal and plant health reasons, and anything that's not personal luggage.
Departure Regulations
Travelers leaving Argentina by air, land or sea cannot carry more than $10,000 or its equivalent in cash, checks or traveler's checks, unless this has been previously authorized by the proper agency. In addition, travelers who carry items from a third country, meaning items from a country other than Argentina or the traveler's native country, should declare those items to customs in order to avoid taxation. Items prohibited from leaving Argentina in a traveler's possession include any items that aren't personal luggage, narcotics, unauthorized firearms, explosives and anything banned for public, animal and plant health reasons (such as seeds and animals).
Customs Taxation
Travelers who don't declare goods that they must declare are subject to taxation on the goods, as well as a fine for neglecting to make the declaration. Moreover, customs agents have the right to confiscate undeclared items. Travelers entering with brand-new items, such as an unused laptop, should carry the receipt to show to a customs agent. Otherwise, the agent will impose a "unique tax" on the computer, based on what he thinks it's worth, which could be much more than its actual value. The unique tax rate is 50% above the exempted rate for a specific item. Travelers can pay customs taxes by making a deposit at the Argentine National Bank or by paying the customs office via cash or debit or credit card.
just reading all those would inform me to take extra special care, make 100 extra phone calls etc etc....all that was done seems within the rules of their country and alot of them, quite obvious ones, have room for some exploitation by the odd individual.
