Our refineries can still sell gas for a premium in the U.S. until the U.S. production catches up.  Ergo the higher price.  It sucks, but wholesale prices are on the American market price and retail will gouge you, until they are sure they can can get a decent price on their fuel.
Can't blame them.  I'm not too sure I know a lot of rich gas station owners.
There's not a lot of profit margin for them and the volatility can help as well as F them over.
The old Bob's gas stations are pretty much gone anymore.
