We offer automatic shipping rate calculation for USPS, FedEx, and UPS shipping methods. You may enable or disable any of these methods by navigating to your Account > Shipping tab and checking the boxes next to the default options.
All default shipping methods automatically display a shipping rate to the customer during checkout. Rate estimates are delivered back to us in real time from each respective shipping carrier's mail server and account for the destination zip code, origin zip code, order weight, and the shipping service class.
Note: By default, only USPS and UPS shipping options are shown. Support for many FedEx shipping methods is available as well, contact support at support@crystalcommerce.com to request FedEx default shipping options in your shipping page.
