Is that the BC price, or Alberta? Seems high--the SAQ in Quebec has it for $99. But if you are a Lagavulin lover, you'll want to try it at least once.
I'm never surprised by careless errors like "Doublewood" in the liquor industry--not everyone who is making such entries is really into whisky, after all, and even some who are are less than diligent. I can see someone thinking "doublewood" is an accepted generic term.
