With the Stamps.com integration, you can mechanically create ready-to-print transport labels for USPS based on objects in order. Stamps.com seamlessly accesses the ultra-modern USPS prices when developing your tags, giving you exceptional reliability, ease, and speed.
This extension no longer shows transport quotes to your clients during checkout. If you desire USPS costs proven on your site's cart/checkout pages, you also want to buy the USPS Shipping Methods extension. Using these two extensions together, your clients see the great prices at some stage in the checkout, and you take gain these equal quotes when growing transport labels by the backend order admin.
