uShip returns the difference when the dollar amount invoiced by the LTL Carrier is less than the amount originally paid through uShip. The difference is credited back to the uShip account of the person who booked the shipment. 

If you'd prefer to receive the difference back to the credit card used for booking, please email LTLSupport@uship.com, reference the bill of lading number for the shipment, and request that the credit be refunded.
