If you do not want the “Price Reduced” banner to reflect on the portals, simply insert the new lowered price and tick the box next to the price field to disable it (hide 'price reduced' banner on supported portals)
This removes the reduced banner.
Please note regarding Private Property:
Private Property automatically applies the “Price Reduced” banner as soon as it detects a reduction in the listing price. This process is not dependent on whether the banner has been selected on the feed.
If you wish to have the “Price Reduced” banner removed from Private Property, you will need to contact Private Property Support directly at: support@privateproperty.co.za.
Their support team will be able to assist with removing the banner.
