Require Rates from Preferred Carrier - Amazon MWS
When using Amazon MWS as a shipping method, and a preferred carrier's rates are temporarily unavailable this could cost the client a lot of money by using an expensive option. By using "Require Rates from Preferred Carrier" you can prevent the shipment from being completed using any other carrier than the preferred carrier. If the chosen Preferred Carrier fails, the user must try again or choose a different shipping method.

- Navigate to System > Configuration.
- In the left side menu, choose Shipping Methods in the Sales section.
