How to exclude Worry-Free Delivery from discounts?
Due to Shopify's shopping cart system, in order to reflect the change in the amount after adding Worry-Free Delivery to the cart, Worry-Free Delivery must exist as a product in your store. This may result in Worry-Free Delivery may being mistakenly discounted or even applied as a free product when customers use discounts. To prevent this, you can exclude Worry-Free Delivery from discounts.
