Can I see that dusty old bottle in the back there, sir?
Even though I live in Silicon Valley I have not found a good website or listing of local liquor stores with a good selection of scotch. About the best I have found is through YELP. This has lead me to stop at every liquor store along the way to see what each one has to offer. This search has resulted in some interesting discoveries. I was at one "hole in the wall" where one would only expect to find low grade beer and liquor but when one steps in the impression changes immediately. This store was having a **** on Laphroaig 10 for $40. I by chance grabbed a bottle on the back of the self and when I went to the register it rang up at $30 (they had to knock the dust off to read the price).
This left me with the realization that many of the drive liquor stores don't rotate their stock or update their price list for the higher end Scotches because most of the clientele are buying something else. This has encouraged me to freely ask the attendant to get out the step ladder and pull down that "old dusty bottle in the back of the rack" with some nice finds.
Since then, I have found a Macallan 18 for $120. The biggest surprise find was a vintage bottle of Macallan 18 distilled in 1966 and bottled in 1985. The price for the bottle was significantly less than the current market value. When I got home and checked the value on the Internet I was quite shocked at the prices I found.
In short, I encourage anyone with an interest in scotch but that wants to keep as much money in their pocket as possible to venture out of their comfort zone and go to those dive liquor stores (but probably during daylight hours).
