This is the kind of route where you can ship cheap and fast without compromise.

Cheapest Option by Package Size
- Small packages (under 1 lb): USPS Ground Advantage at ~$3.25–$4.25 is the cheapest way to ship. First-Class Package Service handles items under 13 oz at similar rates.
- Medium packages (1–5 lb): USPS Ground Advantage at ~$4.50–$6.50 is the clear winner. Priority Mail at ~$7.50–$9.50 adds minimal benefit since ground is equally fast at this distance. Flat Rate boxes cost more than standard pricing — avoid them on this route.
- Heavy packages (5–20 lb): USPS Priority Mail at
$10.00–$18.00 remains competitive with UPS Ground ($11.00–$20.00) and FedEx Ground (~$10.50–$19.50). At this distance, all carriers price closely. - Large/heavy packages (20+ lb): UPS Ground and FedEx Ground charge ~$20.00–$40.00. USPS stays competitive up to about 30 lb. For very heavy items, consider freight shipping options or regional carriers.
Delivery Time Comparison
| Speed Tier | USPS | UPS | FedEx |
|---|---|---|---|
| Ground / Economy | 1–2 days | 1 day | 1 day |
| Express / Priority | 1–2 days | 2 days (2nd Day Air) | 1–2 days (Express Saver) |
| Overnight | 1 day (Priority Mail Express) | 1 day (Next Day Air) | 1 day (Standard Overnight) |
At 175 miles, ground delivery is effectively as fast as express service. UPS and FedEx Ground frequently deliver next business day, and USPS Ground Advantage usually arrives in 1–2 days. Paying for express is almost never necessary.
Tips for This Route
- Never pay for express service. Ground delivery on a 175-mile route is 1–2 days with every carrier. Express and overnight services charge a large premium for no meaningful speed advantage. Save the money.
- Skip Flat Rate boxes entirely. At Zone 1–2 pricing, distance-based rates are at their lowest. Flat Rate boxes will almost always cost more than standard pricing for this route.
- OnTrac is a strong alternative. OnTrac operates throughout the Portland-Seattle corridor with some of the lowest rates available. Many shipping platforms offer OnTrac as a default option for Pacific Northwest deliveries.
- Consider regional couriers for same-day. Several courier services operate between Portland and Seattle, offering same-day delivery for urgent shipments. If you need delivery within hours, these services are practical given the short distance.
