Jacked up prices on gas and the women that work there are rude as hell. They also over charge you for soda refills. I only would come to this location to use my Smith's Reward points, but their gas prices are so high that it negates any savings from the Reward points.
Avoid Green Valley Grocery and go to Terrible Herbst. Even without reward points, Terrible Herbst is less expensive! You also get a lot better service from friendlier clerks at Terrible's as well!
