Wow, $50 for 3 little bottles? That's insane.
I think it was the 21 that put it over the top. Take that 1 out of the equation and the price would drop down significantly I bet.
I've found that once your single malt becomes old enough to vote, the price jump is completely disproportionate to the increase in quality.
Macallan 12, while not cheap, is still doable once in a while, esp if you get it on sale. I dont guzzle it like Budweiser. I've seen Macallan 18 for well over double the price, depending on where you look. For me, it's better, but not THAT much better. Maybe I'm just not enough of an expert to appreciate that difference. Last time I had some was a shot at a restaurant on the companies dime a couple years ago.
