WooCommerce Stamps.com API Plugin
WooCommerce Stamps.com API Plugin extension does not display shipping rates to your customers during the checkout process. If you want USPS rates shown on the cart/checkout pages of your site, you need to purchase the USPS Shipping Methods extension as well.
This is exactly the same file distributed by WooCommerce, but we don’t offer any additional author services like technical support and license (read our FAQ for more Info).
