Tbh I'm doubtful it would be in all stores so I wouldn't make a special trip but if you're passing your local Coop it might be worth popping in to see if they have any reduced spirits.
The Laphroaig was the best bargain but they had others reduced too.
Russian Standard Vodka £6.02 35cl
Hendricks Gin £23.19 70cl
Glenfiddich £10.72 35cl (boxed)
Smirnoff Lime £10.05 70cl
Peach schnapps £5.??
Sambuca Octva £10.22 70cl
Special reserve Port £4.75 70cl
Others including Jim Bean, Chivas Regal and rum and couple of other whiskys (can't remember brands)
