Compare two products by price per unit to find the better deal, regardless of package size.
Each product's total price is divided by its quantity to get a price per single unit (per ounce, per item, per liter — whatever unit you're comparing in) — the lower unit price is the better value, even if the total price or package size looks different at a glance.
