The Free Shipping Notification appears on the Shopping Cart Page. This notification works with Sitewide Free Shipping discounts only. The Sitewide Free Shipping discount should not have any target items. The target items should "Include all items".
Free Shipping Notification will not work for Coupon Code-based Free Shipping discount codes.
When the cart meets the Free Shipping discount condition like Usage & Shipping Country, the system will automatically display the Free Shipping Notification informing the customer how close they are to receiving the Free Shipping, motivating them to increase their cart size.
Example: Sitewide Free Shipping is enabled with a Minimum Purchase of $100. When the customer adds items to their cart and the subtotal is $19.99, the system will automatically display the Minimum Purchase Reminder: Add $80.01 to get free shipping on the Shopping Cart Page.
