Costco in Seattle (4401 4th Ave S)

Buying gas st Costco is the cheapest most anywhere. They're first for the cheapest price in this South Seattle/Sodo area. I live just about 5-6 minutes away so I buy gas when I can. Secondly, if you are looking for cheap gas there's a pump only non-attendant gas station on W Marginal Way and another one on 1st Ave S in the White Center area. Thirdly, the next cheapest stations are the Arco on Rainier Ave & McClellan, the Safeway gas station on Rainier Ave & S Charleston (just about 5 min away) and another Arco on MLK Way & S Orcas (a cross the 7-11 store). Download the "GAS BUDDY" app onto your phone and it will tell you the cheapest gas station closeby to your current location. Of course these locations I mentioned here are more in the Sourh Seattle area, South Sodo area, the White Center area and kinda the South Park area. Happy gas buying for cheaper prices.

Cheapest place to get Premium gas. Lots of pumps so the line moves very quick but they also make sure you get in and out fast too.

Always the lowest prices around

Best gas price at all times!

one of my favorite places to stop. Good prices, good people, even a bite to eat if you need it. This Costco even has a car wash!

Good price

Great prices and great service!

Excellent quality fuel with the best price

What you can expect from a Costco in south Seattle. Cheaper for the area plus the best part is the car wash! Wish all Costcos had a carwash.

It’s awful, don’t get gas here, leave it all for me :P
