Macallan 12 is $100 now?! I believe it, but back when I was first getting into scotch, it was $30-$35 a bottle. Inflation accounts for $16 of that, but the rest is insanity :^D
edit:
For a frame of reference, we'll pick 1998. That was when my daughter was born, and I had been into scotch for a few years at that point. There were some gems for around $25. Solid scotches could be had for $30-$50. You could get something really special for $60-$80, and over that was extravagant. Now, you pretty much have to hand over a $50 to get in the door, and the prices rise quickly. We have a local liquor store that has bottles of whisky $1.5k+ on the open shelf. That still blows my mind. That kind of stuff used to be behind the counter, and/or in a glass case. Really makes me feel like a piker when I'm browsing whisky :^D
