How current Spokane Valley prices compare
Costco Spokane Valley prices are typically set a few cents below major brand stations and are monitored daily by regional gas price aggregators, which show this Costco gas station often ranking among the lowest-cost options in eastern Spokane County.

"Costco often offers many savings opportunities, including at their pump with up to 30 cents cheaper fuel compared to other gas stations," wrote budgeting expert Andrea Woroch, underscoring why members in markets like Spokane Valley increasingly treat the Costco gas station as a primary fuel stop.
Recent trends driving 2026 prices

By early 2026, however, crude-oil volatility and regional pipeline constraints pushed the Spokane Valley Costco average above $4.50 per gallon before the current mid-$5.10s range stabilized in April and May.
