Honestly Duty Free is not a great bargain for US residents. Most countries have much higher VAT, Luxury and/or alcohol taxes than we do. Maybe perfumes are a bit cheaper, but seems to me that most warehouse (Costco, Bottle Barn) prices on liquor is pretty similar, certainly close enough not to deal with schlepping bottles around. And remember, you can't carry duty free on to a domestic flight - so unless your international flight is your last leg, you'll be checking the booze into your luggage.
