Love this OT thread.
For the whisky afficionados, supermarkets mostly offer slim pickings, at the higher prices you can get the aged single malts far cheaper on line e.g Ardbeg. For value, I recommend The Ardmore which you'll find at around £20-25, if you like a slightly smokey whisky.
If you have a Cost Co card then you should buy the Laphroaig Quarter Cask at around £30 and Lagavulin 16 at around £40. These are excellent whiskies and in the case of the Laga, one of the best regarded ever. You would pay upwards of £50-60 in the supermarkets.
For budget blends, by far and away the best for value and quality is Black Bottle, at around £15-20. It's as good as many single malts. In England though, you'll have to go online , Amazon or master of malt / the whisky exchange is the place to go.
