Costco in Fullerton (910 S Harbor Blvd)

This station is one of my favorite station because it is usually the least expensive per gallon station in my area.

Don't waste your time. Always long lines

Cheapest gas around

Long lines. But anything to save 20 or 30 cents a gallon, right? At least the lines move somewhat fast.

Wonderful Customer Service

The price went down since Monday!Amazing

looooong lines

This place is awesome just needs more guys making sure the line moves Costco needs to be worried about the traffic they create for others

Best prices in So Cal. Always competitive with Sam's Club in Fullerton.

Long lines, but the prices are $1.23 cheaper than the other brands! Totally worth it.
