When we buy in bulk, so the 4L we pay less. If we bought smaller units, say in cartons, per unit would cost more. Similarly to how your 1 gallon jug costs less than the cartons likely.

That’s even more confusing, so even though your “gallon” of milk is actually several “quarts” it’s priced as though you bought one large package? (I know 4 liters is more than 1 gallon but our biggest container is a gallon fallowed by half gallons and quarts)

Why wouldn’t retailers/wholesalers charge the same for the same product?

I mean it’s cool I’m not criticizing it, if i could buy 2 1/2 gallons for the same price as 1 gallon that’s what i would do it just doesn’t make sense from a business standpoint.
