USPS: USPS Ground Advantage is usually the lightweight winner — work-share access lets us inject parcels deep into the USPS network for additional savings.

FedEx: FedEx tends to win on transit reliability for time-definite commitments at the cost of higher rates.

Optimizing your costs on this corridor
For shippers running this lane regularly, here's where the cost optimization shows up:
- On coast-to-coast lanes, even small dimensional inefficiencies compound — a 2-inch larger box can shift you to a higher rate band.
- High-zone parcels benefit most from regional injection: instead of dropping at the origin Post Office, parcels enter the USPS network closer to destination, effectively reducing zone.
