“Gas prices continued to soar in a majority of the nation over the last week as oil’s meteoric rise pulls gasoline and other refined product prices higher. But, there may be some light at the end of the tunnel,” said Patrick De Haan, head of petroleum analysis for GasBuddy. “The sharp rise we’ve seen over the last three weeks should begin slowing down soon, barring another jump in the price of oil.”
