I found the map on the GasBuddy app, and it does help to find areas when i am driving where gas is cheaper, but it still really does not make sense. I think the media is right that the gas companies are making horrible profits. Don't know about profits for individual gas stations or chains.
Today, I used the GasBuddy ap and discovered that I could drive 120 miles from Amargosa to Boulder Beach Campground or I could go through Pahrump which was a drive of 129 miles. (The only station in Amargosa charged $5.95.) I have a 55 gallon tank which was almost empty. A few stations in Las Vegas were about $4.99, but the vast majority were $5.29 - $5.85. Gas in Pahrump was around $4.06 - $4.75, with several around the lower number. I drove the extra 9 miles and went to Maverick's south of Pahrump and paid the cash price of $4.06 by using my debit card. I bought 48 gallons of gas, which saved me at least $48 in gas!! And I did not feel guilty filling it up!!
The good news is that GasBuddy was accurate for the Pahrump stations I noticed. Pahrump, by the way, has about 10 or so gas stations, so it is not a tiny town. I really found this map helpful in seeing the overall picture:
