For item values below $30, your shipment is automatically protected free of charge. For shipments valued more than $30, the cost of Total Shipping Protection is set as a percent of the total order value, plus shipping cost. The fee is calculated per shipment and is returned in your quote from BoxC and it’s also displayed when you sign up to the program.
Rates are shown in the Total Shipping Protection wording, available when you edit a shipment or when you set up Total Shipping Protection.
