If you're referring to "750 ML Cask Strength - 29 yrs," for $339.99 it had better be good!
Gads, at that price, it would bring one to tears to un-cork it - let alone drink it.
For special occasions I'll break out the Glen Fiddich and Glen Livet, otherwise I'm happy with Dewars.
Nah, I drink the 15. (which is still not cheap, about $50 a fifth)
