What are digital products?
Digital products are "items" that are part of a marketplace order that ShipBob will not fulfill. These SKUs can include online coupon codes or physical products that we do not warehouse. Marking these items as “digital” will automatically remove them from all order details and prevent orders from going to exceptions.
