Best recent purchase was Auchentoshan, American Oak cask, at Tesco's a few weeks ago - £23 for a 75cl bottle - but I nearly made a costly mistake, as they had more than one Auchentoshan, and the other one was over £10 more. Fortunately, being a suspicious b#gger, I always check my bill before leaving the store, and spotted the higher price - and was able to exchange for the bargain bottle - which is very nice!
Currently enjoying a wee dram o Glen Moray - Speyside single malt from Elgin.
