Here's my question. Why are gas stations allowed to raise their prices to current levels when the gas that's in their underground tanks was purchased at a much lower price?

Here's some hypotheticals: Let's say their last delivery was 3 days ago and they paid $2.25/gallon. Their mark-up is .25/gal. so the price to the consumer is $2.50. Why are they allowed to bump up the price 50 cents overnight (current price here in Louisville is $3.19)?

Somone might say that it protects the station from when the prices fall, but in my eyes that's the cost of being in that sort of business. If there's some logical explaination, I'd love to hear it.
