Cheapest Option by Package Size

- 1-5 lb: USPS Ground Advantage at ~$7.50 to ~$14.00 consistently undercuts UPS and FedEx by $5-$6 per package.
- 5-20 lb: USPS flat-rate boxes are the top value. A medium flat-rate box ships for ~$16.10 regardless of weight or distance, beating weight-based rates for anything over 6 lb.
- Over 20 lb: UPS and FedEx Ground handle packages up to 150 lb. Above 70 lb, freight shipping services typically reduce costs by 30-50%.

Tips for This Route
- Prioritize flat-rate boxes for items over 5 lb. At 2,760 miles, zone-based rates stack up quickly. A USPS large flat-rate box at ~$22.45 beats the ~$28.00 Ground Advantage rate for a 20 lb package.
- Consider Priority Mail for reliability. The 2-3 day Priority Mail service uses air transportation on cross-country routes, bypassing the ground network entirely. This reduces exposure to weather delays and hub congestion.
- Avoid shipping during peak holiday season. Carrier networks between the West Coast and East Coast are especially congested from late November through December. Ground transit can stretch to 10+ business days during this window.
- Package tightly to avoid dimensional weight charges. UPS and FedEx use dimensional weight on this route aggressively. A box that is even 2 inches too large on each side can increase your rate by 20-30%.
Key Takeaways
- USPS Ground Advantage is the most affordable option for lightweight packages on this route, though expect 5-8 business day transit times.
- Flat-rate Priority Mail boxes are the smartest choice for shipments over 5 lb, neutralizing the zone-based pricing that inflates costs on long routes.
- Priority Mail at 2-3 days is the best mid-tier option for time-sensitive shipments, costing far less than overnight air.
- Tight packaging matters more on this route than shorter ones, since dimensional weight pricing from UPS and FedEx hits harder at higher zones.
