Arlington gas price huge variation

[Anonymous]

So all along Langston Boulevard near Cherrydale. There is an Exxon station where the gas is about $4.23, but directly across the street is a liberty gas station at $3.50. And then less than a mile down the road RSVP a psycho and another Exxon, all with gas prices around three $3.60.

Why in the world is this one so expensive and this one Exxon in Arlington Have such a huge premium? I notice it mostly because it is our most convenient, gas station, and in fact, it had a problem with skimmers a few years ago, but unsure of what is happening here with the market. How can they do that? Is it in the car dealerships across the street?

Also, for a long time liberty did not take credit cards, but it seems like they do now, is there any reason not to use them now?
