I've got a six pack of Bud Light Platinum in the back porch fridge. Been there for almost two years now, drank one, used one for beer battered catfish one time. I have three bottles of Whiskey, had two for about two years and one almost a year. Drank a few from them over that time span. Have one bottle of Red wine unopened for a about year now. So I'd say $0, I don't buy every month.
