UC ConnectShip

This module integrates the Progistics Connectship API as a shipping method for Ubercart. This module is expected to only be used by high volume shippers and requires a dedicated ConnectShip Windows server along with your license. In a nutshell, ConnectShip is a web service that serves as an abstraction layer for every carrier's shipping rate calculation API. This means through one service call you can rate a shipment for USPS, UPS, UPS Surepost, FedEx, Canada Post and Canpar.
