For daily newspapers, it is possible to offer a campaign where the subscriber can freely choose which days they wish to receive the newspaper—up to a maximum number defined in the campaign. It sounds more complex than it is. For example, the offer might be: “Get the newspaper 3 days of your choice each week.” The subscriber then selects which three days they want delivery, from among all the weekdays the newspaper is published.
To configure this feature, you create a campaign custom field and enable the option “Maximum number of weekdays a product can be delivered, if selection is available.” The field must be of the “number” type.
When setting up the campaign, you can then define the maximum number of weekdays that can be selected during order or editing—matching the offer the campaign provides.
