First make sure that you have selected a carrier, carrier service, and packaging type. This can be easy to miss sometime.

If you have entered all of your shipment information on the READY TO SHIP page but you are not getting a rate, you might have a problem with the information that you have entered as your "Ship From" address.

Please check your "Ship From" address within your store settings page. Usually, a rate cannot be calculated if your "Ship From" address is incorrect. Reconfigure your address and try again.
