On my way to AC, I found the Duty Free shop to be the best deal around for non local spirits. I stocked up on extras and figured even with the tax, it would be less expensive than buying locally, ie, a 1.75L bottle of Absolute was $26 US at Duty Free and last time I looked, a 1L bottle was $40+ US in AC. Now, that being said, Rum is my new favorite drink, especially the 1 Barrel, and very inexpensive.
