The USPS Simple plugin adds a new delivery option to WooCommerce – US postal service. Each item is packed individually, then items’ delivery prices are summed up. Regular-sized items can be grouped by their weight. The USPS API is used for the delivery price calculation. USPS Simple allows to calculate rates for domestic shipping only. WooCommerce currency must be set to US dollars and base country/region must be the USA.
