Cart price rules can be applied on schedule as part of a campaign and grouped with other content changes. You can create a campaign based on scheduled changes to a price rule, or apply the changes to an existing campaign.
All scheduled updates are applied consecutively. This means that any entity can have only one scheduled update at one point of time. Any scheduled update is applied to all store views within its time frame. As a result, an entity cannot have different scheduled updates for different store views at the same time. All entity attribute values within all store views, which are not affected by the current scheduled update, are taken from the default values, and not from the previous scheduled update.
If there are multiple price rules running in the same campaign, the Priority setting of the price rule determines which rule takes precedence. To learn more, see Content Staging.
Keep in mind the following caveats:
Campaign Start Date and End Date must be defined by using the default Admin time zone, which is converted from each website’s local time zone. Consider an example where you have multiple websites in different time zones, but you want to start campaign based on a US time zone. In this case, you need to schedule separate update for each local time zone, and set Start Date and End Date converted from each local website time zone to default Admin time zone.
