Same here, plus they give an additional discount if you shop at their store, from the already low price - usually the lowest around.The closest place happens to be the cheapest place (99% of the time), so it's the place I fill up every time. All of the above.
It's much better to buy gas from the other chains who get their oil from Saudi Arabia, where everyone is free and there's no severe human rights violations, oppression, gender apartheid or women getting stoned to death for being raped.
Nice try, no one is taking the bait.
