Current Snapshot

This positions it $0.41 below the Washington state average of $5.76/gal while exceeding the national benchmark by approximately 15% due to Pacific Northwest logistics costs. Local stations range from $5.25 to $5.47/gal, with independents like Hamilton Market occasionally undercutting majors.

- Local price wars: Independents vs. majors could shave $0.20/gal, as in Dec 2025 Hamilton-Mobil clash.
- Federal policy: Trump's 2025 reelection tariffs on imports may add $0.05/gal long-term.
