The following additional configuration is possible with Premium Matrix Rate:

• Ability to calculate shipping based on tax inclusive cart price
• Ability to allow custom sorting on shipping rate (default is lowest->highest price)
• Global Free Shipping Minimum order amount (also able to configure this on a per zone/weight/price basis within the csv file)
• Option to change error message output when no rates found (or not display any at all)
• Option to add a handling fee

This is all managed within the shipping method configuration.
