Why is the shipping charge for this item based on 70 pounds, if the item only weighs 30 pounds?
If your package has a large size-to-weight ratio, your package may be billed at dimensional weight rather than actual weight. Dimensional weight is calculated by multiplying the height in inches, by the length in inches, by the width in inches. Round each measurement to the nearest whole inch. The resulting total is the cubic size of your package. Divide the result by 194. This is the dimensional weight.
