AUD$6.10 for a gallon of the cheapest possible milk I can find within 30km/20 miles here in Australia.

USD$4.00 even… Again for the cheapest possible 12 pack 1L UHT generic milk.

If you want something from the supermarket fridge you’re gonna to need to start at multiplying that by 1.5 to 2x .

So USD$8 /gal might be fairly typical here.
