The flat rate module by state zone allows you to specify different shipping rates based on the method of
shipping AND at a flat rate AND the state the item is being shipped to. This module evaluates
the "ship to" state and only displays those methods and rates applicable to the destination. This prevents
customers from selecting lower rates which may not be available for them. Not compatible with the current google checkout module as that module does not use the customer's address to select the shipping methods available.
The module currently fully supports the mivasql configuration of MIVA Merchant 5. It also supports MySQL as long as load balancing has the data stored on the single MySQL server and
permissions are set correctly on the data
directories. This would be the case in most of the server setups. If you are using Merchant 5.x and your host is web.com, you will not be able to use this module due to the way they configure their servers. There are no known issues with
other hosts.
