OOPS! That last bit REALLY burns me though. If somebody had mistakenly paid TOO Much, I bet there's no way in hell the gas station would send a refund. "Oops! We had the price set at $2.75, when it SHOULD have been $2.57 - Here's your refund!" The Store offered a price. Consumers took them up on the offer. If a person had come in BEFORE and asked about the price, the store would have been within it's rights to refuse the sale - but after the fact? Too late.
