DULUTH – It was day three of feeling pain at the pump Friday.
Minnesota was the most expensive place to buy gas in the country.
Minnesotans are paying an average $4.15 a gallon and in the Twin Cities it's the highest in the U.S. at $4.28.
Honolulu comes in second place and Chicago in third.
The spike is hurting Northland delivery drivers.
For workers at Pizza Hut in Duluth, the high prices are affecting their personal budgets.
Paying more for gas per delivery means less money in their pockets, but there is a silver lining.
"Tips have gone up a little bit, not quite the same as the gas prices, but people are noticing that, and know the drivers are paying more, so they do tip more usually," said Gordon Maukstad, a delivery driver at Pizza Hut.
Prices are so high because two oil refineries in Chicago have shut down production.
They aren't expected to reopen until mid-June.
