In Costco yesterday and made a note of their prices which include VAT
The Glenlivet 12 year old 18.27
Macallan Fine Oak 10 year old 18.34
Glenfiddich 12 year Old 18.34
Glenmorangie 70cl 10 year old gift set inc 2 whisky glass 20.68
Lagavulin 16 year old 32.12
I believe these are quite a lot better than you can normally get elsewhere.
