Neto’s shipping matrix has the option to offer routing groups - a way to group shipping methods together and show only the cheapest option of that group. You can group all of your shipping options together and show one low cost or you may want to group the options into categories, for example, standard and express, to offer your customers the cheapest option of several services.
Routing groups are displayed in the column “routing group”
To add a routing group
The routing group number will now be displayed in the routing group column and only the cheapest option from all the methods in the group will be displayed at check out. Options not in a group will display as normal, provided that they are set to be visible on the site and that the order meets all shipping requirements (item can be shipped by the service, to the location, etc).
You can change the sort order of your shipping methods by editing the sort order value against each method.
