Tips for This Route
- Ground service is fast enough for most needs. With two- to four-day ground transit, paying for express shipping is rarely worth it on this route. Save the upgrade fee unless delivery is genuinely time-critical.
- Use USPS flat-rate for heavy items. Priority Mail flat-rate boxes ignore both weight and distance. A large flat-rate box at ~$22.45 can save $5-10 compared to weight-based pricing for packages over 12 lb.
- Drop off early for same-day processing. Both San Francisco and Seattle have major sorting facilities. Packages dropped off before the last collection time (typically 4-5 PM) get processed the same day, which can shave a full day off delivery.
- Negotiate rates if you ship regularly. Both UPS and FedEx offer negotiated rate agreements for shippers moving 10+ packages per week. On this volume corridor, discounts of 15-25% are common.
