Yeah, since I retired I drive maybe 3000-4000 miles a year. When I gas up, I usually shop for best price for Top Tier-rated regular.
Costco is usually the winner but the lines can be long and most times I don't have the patience to sit there watching the dim bulb at the pump trying to figure out how to get his cards in the slot or use his phone app to start fueling.
Quik Trip, another Top Tier brand, used to price pretty aggressively but they don't any more in my area. Sometimes I'll just gas up at Sam's Club even though it's not Top Tier...but the lines are usually much shorter than Costco.
