Costco in Seattle (4401 4th Ave S)

Best Price in town

The lines are incredibly long and getting out of the lot into busy 4th Ave is difficult. Prices are not competitive if you have rewards from Safeway or Fred Meyer.

Cheap and fast.

I buy 95% of my gas from COSTCO

Nice station with many pumps. usually only short wait

Cheap gas, fast lines but bathrooms are far away in main building.

Always the lowest prices and the car wash is a bargain.

Least expensive gas around with lots of pumps and a car wash.

Consistently low prices, top tier gas

Cheapest gas around, fast lines and very clean.
