I bought some 10 year old Tawny Porto aged in wood cast, sold under the Kirkland Name, for about 12.00. Good Stuff.
As for their Booze, I think it depends on the state and whether they have a license to sell in that state.
Rum..??? I don't know.
They sell liquor in our area, and we usually buy Sobieski Vodka. 1.75 Liter made in Poland, Triple distilled for 19.00 and some change. Good stuff. Not Grey Goose, but better than Absolute.
