USPS Simple is a free shipping plugin for WooCommerce that provides accurate, real-time USPS domestic rates to your customers. These rates are calculated based on the customer's shipping address and the size and weight of the items in their cart. By default, the plugin calculates the shipping price for each item individually, simulating separate shipments for each one. The total price shown to the customer is the sum of these individual item prices. For regular-sized items, there is an option to group them based on their weight. When this feature is enabled, the dimensions of the grouped items are disregarded in the rate calculation. This helps reduce the shipping cost for orders with many small items in the cart. Fully functional right after installation. Supported services Priority Mail — Regular non-flat rate — based on weight, size, and zone — Small Flat Rate Box — Medium Flat Rate Box — 1 (top-loading) — Medium Flat Rate Box — 2 (side-loading) — Large Flat Rate Box First-Class Mail — Postcard — Letter — Large Envelope USPS Ground Advantage Media Mail Library Mail
