WooCommerce USPS Shipping Method v5.6.6 Plugin
The WooCommerce USPS Shipping Method is a plugin that provides real-time shipping rates from the United States Postal Service (USPS), the largest delivery network in the United States. This integration allows you to automatically display accurate shipping rates to your customers.
This plugin is designed to work with US Dollars as the currency and the United States, US Virgin Islands, or Puerto Rico as the base country. It supports inches (in) and pounds (lbs) as units of measurement, with the ability to convert to other units automatically.
Additionally, the plugin gives you the ability to enable or disable specific services, edit their names, and add costs to them. You also have the option to pack items individually or use the built-in box packer for more efficient shipping.
