Although the greater Vancouver area seems to be perpetually higher than elsewhere, I think the current prices are exacerbated by some refinery maintenance shutdowns. I think Cherry Point in Wa state (where we get some of our gas from) just got back up and running.
I just filled up today and paid #171.00-ish/litre (for 89 grade). Cost me about $150. Having said that, I usually ignore the prices and probably wouldn't drive any distance out of my way to save a few bucks. I just think of it as the price of driving.
