You can charge your customers a flat shipping rate for any order, regardless of quantity. This is useful for merchants who want to deliver products themselves or offer their own fixed cost for different delivery methods such as Standard Ground or Express Overnight.
You can also charge a flat rate based on how many units of a product are in the cart if quantity matters or you need to charge extra to ship certain (e.g. large or fragile) products.
