This setting is designed to prevent double shipping charges when orders involve multiple locations or different shipping profiles. By enabling it, customers will not be charged shipping costs multiple times for the same order, ensuring a smoother and more accurate checkout experience.

NOTE: This functionality works only with flat-rate shipping that does not include any conditions. If your shipping setup includes conditional rates or subscription-based products, this setting alone will not apply. In such cases, we recommend installing our other app Shipfy.
