it fits it ships cost

it fits it ships cost refers to the pricing system used by USPS for certain types of flat-rate shipping services. The “If It Fits, It Ships” pricing model allows customers to ship items in designated boxes, with a fixed cost regardless of weight (up to a certain limit). This service is often used for shipping small to medium-sized packages at a predictable cost, which makes it easier for businesses and consumers to budget their shipping expenses. The flat-rate boxes are available in several sizes for different shipping needs.
