To utilise your promo pricing from product cards there a 2 different ways to set it up on listing rules template.
1. Under field mapping tab link price to Promotional Price Group and revise all listings. Note that they will always use Promo Price even when promo period is finished.
2. Under field mapping link price to Current Price Group. What this does is use standard price say Price A when not in promo period and then Promo Price A when in promo period. This is a more streamlined process as listing price revises automatically.
