This USPS Shipping Plugin for WooCommerce provides integration with USPS Web Tools and your WooCommerce website. It is able to provide live shipping rates directly to your customers in their shopping cart as well as at checkout. It, also provides up-to-date package information from USPS’s Parcel Tracking service. It can be used to ship within USA as well as Worldwide.

Parcel Tracking Service

Package Tracking is available when you enter the PIN (Parcel Identification Number) or Tracking Number into the customers order details. This plugin will automatically look up the most recent and up to date event information available for your order from USPS on a daily basis. You can set an automatic email notification to be sent to your customer when the package is mailed or delivered. The tracking information can be set to allow your customer to receive up to date information on their order either as an email notification and/or at your customer order page.

Live Shipping Rates in the Shopping Cart

This shipping plugin uses the product’s weight and dimensions to calculate the most accurate shipping rates. For the rates to work, product weight is required but product dimensions are optional. The shipping cost can be calculated with boxes, if configured.  If desired there is the option to add a mark-up rate to shipping charges.
You are able to choose which services from USPS you want to offer your customer (ie. USPS Retail Ground, USPS Priority Mail, USPS Priority Mail Express, etc).  There is also an option available to provide estimated Delivery Dates if needed. The shipping charges will be calculated and displayed using current and live rates directly from USPS. 
An additional feature gives you the option to set up custom Flat Rates; which gives you the ability to set a flat rate for standard envelopes or parcels that you use for shipping.
