Carrier comparison: USPS, UPS, FedEx
When picking a carrier for the origin-to-destination lane, weight class is what usually decides.
USPS: USPS's flat-rate boxes can be the cheapest option for dense, heavier items in the 5–20 lb range when they fit.
UPS: For B2B shipments on this corridor, UPS Ground is usually the safest combination of price and reliability.
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:
- 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.
- On coast-to-coast lanes, even small dimensional inefficiencies compound — a 2-inch larger box can shift you to a higher rate band.
