Tips for This Route
- Prepare for mountain pass delays in winter. The I-90 corridor through Montana and Washington crosses multiple mountain passes that can close during severe winter storms. December through February shipments may experience 1-2 day delays on ground services. Use expedited shipping for time-critical packages during these months.
- Take advantage of Seattle’s robust pickup network. Amazon Locker, UPS Access Points, and FedEx pickup locations are widespread in the Seattle metro area. Directing packages to these locations reduces missed deliveries and theft risk in urban neighborhoods.
- Use USPS flat-rate boxes for maximum savings. At Zone 8 distance, flat-rate pricing delivers its greatest advantage. A USPS Priority Mail Medium Flat Rate Box ships for ~$16.10 regardless of weight, beating per-pound pricing for anything over about 6-7 lbs.
- Factor in Washington state sales tax. While not a shipping cost per se, shipments to Seattle may be subject to Washington’s 10.25% combined sales tax rate. Ensure your invoicing accounts for this if applicable.
