Prices have gone completely apeshit, so I'm doing my best at estimating here. Also tried to limit it to stuff I think PA carries. Balvenie Doublewood 12 should be $50. Apparently it's $74 at Total Wine now????
Speyburn 10 $30
Compass Box Glasgow Blend $35
Monkey Shoulder $40
Glennmorangie Original $35
Glenfidditch 12 also comes in a 375, which might be helpful since you're unsure.
If prices are appropriate then try these, but I am very concerned after seeing the Doublewood price:
Talisker 10 This stuff is downright briny.
Arran Sherry Cask
Bruichladdich Classic Laddie
Bruichladdich Port Charlotte 10
Bunnahabhain 12
Control states like PA also end up putting tasting sets out on Clearance sometimes, which is a nice way to try things.
I would read some tasting notes because there's huge variation here. I've seen Glasgow Blend described as "Band Aids and asparagus" by someone who liked it for example. It can get weird in a hurry.
