Denver's retail gasoline monopoly

Well, it didn't take long for ConocoPhillips' takeover of BP gas stations a couple of weeks ago to have a negative effect on the retail gasoline market in Denver. The latest report on denvergasprices.com shows that 12 of the 15 highest prices are at Conoco or Phillips stations. The Conoco and Phillips stations nearest me have raised their prices twice in the last 3-4 days, for a total increase of almost 25 cents per gallon.

I'm sure there is no collusion or price-fixing involved. Of course, if you believe that, I have some pre-war intelligence about WMDs in Iraq for sale -- cheap!
