We have benefited from the GS discount at many different Pilot stations. We use the ap, Gas Buddy, to find if there is a lower priced station in range, and check with a Google maps to see if we might have a problem getting in and out.
Murphy is often the lowest price, but can be impossible for our Vegas and towed car. Pilot has often been at or near the lowest in many areas, but not always.
I think we need to stop calling it "working from home" and start calling it "living at work!"
