Carrier comparison: USPS, UPS, FedEx

For shippers running this lane regularly, carrier selection should follow a clear weight-and-zone framework.

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.

Transit time and timing considerations

Most ground shipments complete in 2–3 business days, with two-day air available where speed matters more than cost. Service-level commitments are guidelines — actual transit varies with weather, carrier capacity, and seasonal volume. When the shipment must arrive on a specific date, booking expedited service with a money-back guarantee is the right call.
