just got back this morning from o/s and was browsing the duty free on my way out at Tulla airport. I blind bought a one litre bottle of Galyva and Jameson's Whiskey for $65. If you buy 2 bottles of Glayva it's a 40% discount off the normal duty free price.
I did some research when i got home and noticed the Glayva is $46 for 500ml at Dan Murphys so do the maths (that's 65% cheaper for those who're too lazy to do the maths). It also has very good reviews on Dan Murphy's website.
Only available if you're entering or exiting the country, yes?
