Same here. I used to buy mostly Arco, but then a "Golden Gate Petroleum" station opened up across the street, and they don't charge the extra 35 cents for using a debit card, so I started going there. But I've also gone to 7-11 (Citgo) and even other "no name" stations if it was "time to fill up" without making any effort to find anything other than a cheap price.
A couple of tanks ago, I needed gas and the station available was a Shell station. I knew the price would be quite a bit higher, so gritted my teeth & filled it up. But I was also curious, as I've heard over the years that Shell gas gives much higher mileage. But in the end, I don't think it made much difference - the tank before was higher mpg, and the tank after was about the same. Of course, there was no rigorous testing involved - just my day-to-day driving, always trying to get the best mileage I can...
On a related note, I was once warned that using Arco gas would "ruin" my engine in addition to yielding worse mileage. My "old" Jimmy - the '85 I drove forever - had almost exclusively been fed Arco gas since the day I bought it new. I gave it to my parents a few years ago when I got my "new" 2000 Jimmy, and they still drive it!! The engine has never been overhauled even once in almost 30 years and, without hypermiling, it always got 25 mpg on the highway (EPA said 18, as I remember). So it's gonna be hard for anyone to convince me that Arco gas will "wreck my engine" OR yield bad fuel economy!
