Glen Dean hits the nail on the head with his post about gas prices. I guess it's possible that consolidation of refineries may inflate the price, but the main reason that gasoline continues to go up is supply and demand. He notes some issues that lead to higher prices, including the difficulty of building new refineries. I'm not sure how he feels on the subject, but I'm glad that refineries are hard to build. They are eysores and they pollute. It is a worthwhile trade-off to have fewer refineries and higher prices.
