“There are two Chevron stations near me with prices similar to Costco or Sam’s Club, and they are closer.”
Costco: 2.26. Chevron: 2.44
Besides, Costco pumps are right next to the warehouse. Couldn’t be closer!
I checked mine - two Chevrons near me which are consistently low - $2.29. The Costco closest to me is currently $2.35.
