Gas at this station is more expensive than other local AMPM's. If you are coming from OrangeCounty, stop at the AMPM on Imperial Highway, next to the 57fwy. It's always atleast .5¢-.10¢/gal cheaper.
They won't honor the coffee loyalty check-in special. Employee said his manager "doesn't do stuff like that" or even know how this special got on here.
