After setting the relevant details for your rate, you a free to establish a set of rules for the rate that will determine whether it should be made available to the customer.
Rate rules are optional - if you set no rules for a rate it will always be displayed to a customer if the zone and range that the rate sits under are matched.
If you wish to add rules to a rate, click the Add new rule group button within the ‘Rate Rules’ panel:
This will populate a rule ‘group’ containing a single rule. You are free to add more than one rule to a group - adding more rules makes that rule group more specific. You can think of rules within a group as having ‘AND’ between each rule.
Additionally you can create any number of rule groups which are evaluated separately. You can think of groups as having ‘OR’ between each rule group.
