WooCommerce Stampscom API 2.0.3

If you use USPS shipping services, this extension is the perfect choice for you. It allows you to create USPS shipping labels. While the Stamps.com API provides access to USPS shipping rates for label creation, these rates will not be displayed to customers at checkout. To show USPS shipping rates to customers at checkout, you need to install the USPS Shipping Methods extension in your store.
