UPS: UPS Ground tends to win in the 10–70 lb band, especially on commercial-to-commercial deliveries.
FedEx: FedEx tends to win on transit reliability for time-definite commitments at the cost of higher rates.

Optimizing your costs on this corridor
Three things to look at when you're trying to drive cost down on this corridor:
- On coast-to-coast lanes, even small dimensional inefficiencies compound — a 2-inch larger box can shift you to a higher rate band.
- Long-haul lanes magnify every cost decision: zone-skipping injection, parcel-select work-share, and consolidated dispatch can each save 10–20%.
