Dear DiningBuzz Brains Trust , I'd like to pull together our combined knowledge, tips and traps in duty free - especially the drinks retailing.

Would you mind adding your own favourite Duty Free info below?
I'll save this and the next message for an index and updates.
Thanks to MissyDarlin for your attention, too.

Please report the rip-offs, too. Note SJU recently [Feb '10] jacked up prices.
