Gas prices in our neighbourhood dropped about 10 cents/litre. My wife bought gas at about 89 cents, and then when she picked me up from the train station, it had dropped to 79.
Now, gasoline is unlike any other consumer product.
(1) It's sold to the end customers as though it were still on the commodity market. It's prices fluctuate throughout the day based upon external market forces. If wheat futures fluctuate on the open market, the grocery stores don't mark up the price of bread or bagels.
(2) There's no 14-day return policy. If I'm not satisfied with the product, I cannot return it to the point of purchase. This makes sense because it's mixing around with likely somebody else's gas. But, if I buy an item at a store, and the same day they drop the price, they refund me the difference. Gas stations don't do that.
Bah. I hate gas stations.
