Uh...because high fuel costs drive the prices up at Safeway too?
Money spent at Safeway, money spent by Safeway, money spent at the Chevron station all local businesses. Not all costs are passed to the customer. Price is a matter of supply and demand. Cost of production — or in this case — cost to put it on the shelves at Safeway is a factor to manage. People will not pay more for a product than it is worth to them no matter the cost to the business supplying it. Same thing goes for gasoline. It must be worth 4.35 or whatever per gallon because someone is buying gasoline at that price.
