Choosing a shipping choice used to be so easy! Up until recently the line between when to use parcel shipping and LTL shipping was quite clear.
Parcel shipping historically focused on packages that could reasonably be lifted without assistance by an average person. In other words, packages of less than 150 pounds incurred lower shipping charges due to maneuverability.
The line between LTL and parcel shipping is getting blurry: overlap between the two shipping methods makes it confusing to determine which is best for your shipment.
