Providing discounts on products that are already on sale can have a negative impact on your profit margins. It is essential to have the correct settings from the beginning to avoid any potential issues.
If you have sent out promotion codes to your customers and you already have products on sale in your shop, please be aware that the promotion code will still be valid for use on the campaign price. However, this can cause potential issues with your profit margins. When a product is already on sale with a red price, the promotion code will deduct the price based on the campaign price. To avoid any complications, make sure to check the checkbox titled "Exclude products already on sale" when setting up your promotion code in the campaign editor. This also applies to cart-based campaigns.
