Shipping is a Hard Problem, especially when dealing with large volume (bigger than UPS, usually strapped to a pallet) objects, and/or very dense objects (cartons of metal nuts and bolts). You still need to call your freight person and get a quote directly from the carrier over the phone. Low density LTL (less than truckload) is a pretty known quantity and delivering to a known business (like Walmart warehouses) with a loading dock is easy. Delivering two pallet loads of high density metal to a single story engineering office in an office park with no facilities to service an 18-wheeler (let alone allow one to enter/maneuver) is another thing entirely.
