Before you can offer your customers a selection of shipping carriers,you must complete the following steps:
Configure the shipping settings to establish the point of origin for your store.
Configure the settings for each carrier service that you want to offer.
The configuration options vary for each carrier. However, all require the following stops:
Open a shipping account with the carrier.
Enter your account number or user ID, and the gateway URL to their system into the configuration of your store. See Magento Connect for additional shipping services for your Magento installation.
