Stamps.com Labels Extension
Stamps.com enables you to print shipping labels with pre-paid USPS postage. WP EasyCart’s extension connects directly to the Stamps.com API — upgrade to Premium and begin buying and printing postage right from WordPress. Create real pre-paid USPS shipping labels directly from the orders placed on your eCommerce plugin.
Before You Begin
To connect WP EasyCart with Stamps.com, you need a Stamps.com account — the extension links your cart directly to it. Click here to get started with Stamps.com. You’ll also need the extension itself installed: all EasyCart extensions install as new plugins — a very easy task with WordPress.

Purchase Postage
Configured and connected? Time to start processing labels. If you’re low on postage, buy it in your Stamps.com account or by using the “Purchase Postage” menu. We display your account balance near the top for your convenience.
💡 Good to know: This page requests on your behalf to have Stamps.com add postage to your account — no purchase is made by the WP EasyCart system.
