I’ve also wondered about hard liquor. You can get family sized bottles of GOOD rum and vodka at Costco for about 15 bucks.
But then, the things that will REALLY get you through are a large garden, guns/cartridges, solar/wind power and a good source of water.
Better than big bottles would be cases of plastic pints of whiskey.
if you’re going to buy liquor, buy the stuff in glass bottles....just think it makes more sense...and if you have access to a base, the liquor there is pretty cheap without any additional state taxes...military rum comes in plastic jugs however...
