If you have to pay the shipping cost in case of a warranty case depends on the warranty policy of the brand your suitcase is from.
In case suitcase.repair is authorized to provide spare parts on a warranty basis for a brand we follow the brands warranty policy for the handling of your case.
In many cases brands do cover either the cost of domestic shipping (to the country the product has been initially delivered to) or have a certain threshold until which shipping fees are covered regardless of the delivery region. Our service team will provide you more information on the shipping fee after your warranty case has been approved.
