The town nearest me has fuel at 3 chain convenience stores, and one independent. Two of the chains were at $3.21, (one has a six cent savings for using their debit card... I no longer get fuel there.) The independent was at $3.17. The last is at 3.03. I've noted this price differential ever since prices started rising.
I always wonder why people will go out and pay for a fancy vehicle with no regard to fuel economy; then complain when gas prices go up a nickel. Those must be the same who will eat at an expensive, fancy restaurant; then complain about the price of a loaf of bread.
The more essential something is, the less we are willing to pay for it.
