Why does the shipping weight state 30 lbs. or 70 lbs. when the item weighs less than that?
Most major shipping carriers assess additional charges on packages that exceed a certain size (i.e. length x width x height) limit set by the carrier, regardless of the actual package weight, resulting in an Oversize Shipping rate that is calculated using a billable weight larger than the actual package weight. Please note that the weight that appears in the shipper's tracking information may not reflect the billed Oversize rate.
