Costco in Concord (4200 Rusty Rd)

It'd be convenient if they had window cleaner & squeegees available.

Prices always cheaper than any other stations within a 5 mile radius

Only member can use very disappointing

They do not sell coffee at the pumps or have a restroom, all of that is in the store.

Quick and cheap but have to use Visa or debit only:(

nice place

Best gas prices around!

Lowest price! Lines are long but goes quickly

easy to get gas and always the best prices. sometimes its only a few cents, most times its much better.

moves fairly fast
