You can configure time sensitive Price Rules, i.e., Early Bird Pricing or seasonal sale pricing. This Price Rule will be active starting on the date specified in the Start Date field through the date specified on the End Date field.
Navigate to the Items tab and Select the item that will receive discount pricing.
Click the New Price Rule action. The Price Rule wizard will open. The DEFAULT price will already be listed.
In the Price Rules wizard, in the Name and Price fields, Enter a name and a price for the item.
Check the Is Active checkbox.
In the Price Rule Criteria section, set a Start Date and End Date - the Price Rule will be active between these dates.
