Surprisingly the cost of gas is usually very close in price to Costco, but the location is much more convenient. I usually take advantage of the car wash (which does a good job) and then get an extra $ 0.10/off per gallon of gas.
This Shell is way better. Less chaotic. Cleaner. Convenience store is well stocked.They also have a car wash that I might try one of these days. Easy in and out since it’s closer to the 25 Freeway.
