When using USPS Retail Ground, how is the pricing typically determined?

The correct approach to determining pricing for USPS Retail Ground is based on both zone and weight. This means that the cost of shipping a package varies depending on its weight and the distance it must travel, which is categorized into zones. Each zone corresponds to a specific geographic area in relation to the place of origin. As the weight of the package increases, the shipping cost also increases. Additionally, the zone indicates how far the package is being shipped; thus, longer distances will typically result in higher shipping costs.

Options that focus on flat rate or weight alone do not take into account the importance of the distance the package is traveling, which is a critical factor in determining the final shipping price. Dimensional volume, while relevant in some contexts, does not solely define the pricing structure for USPS Retail Ground. Therefore, considering both zone and weight provides a comprehensive and accurate understanding of how pricing is set for this shipping method.
