I just checked my local "government run" liquor corporation flyer to see what specials they had on (Scotch-specific, of course) and this is what I found:
McCallan $51.60 (save $3.00)
Glenfiddich $30.69 (save $2.00)
also had some Gibsons and J&B Rare, but nobody cares about those
Of course those are Canadian prices, so... you do the math. Anyway, I might have been a little off on my $75/bottle for Oban, but I have a feeling it's not under $50 here. Gotta love the Canadian sin-tax.
And all this talk of collecting various bottles has me with the urge to go shopping!
