One other item, can any one explain to me if the term "Duty Free" is more than just a buzz word to drag in tourists? In whatever country you are in, they don't give a hoot what you buy. Where the "duty' comes in is when you return to the states and they asses the value of the item(s). Whether they were purchased in a duty free store at an airport (which is convenient) or anywhere else is irrelevant. If you have a receipt that is not way out of line, there should be no problem. If it is booze, it is covered by volume, not price. The idea that everything is automatically cheaper in a duty free shop is totally false. Shop for price.

Been there, done that, the washing machine ate the T-shirt
