BP alive and well here in South Carolina and I have many in my area. (and the rest of the country, read on)
AS a general rule in my area, they always have great prices on gas and premium gas is priced well. WAY better then Shell stations here.
Anyway, almost every gas station is part of a franchise. Fuel companies rarely if ever own the stations.
I suspect in the areas that have gone to Conoco/Phillips some smart negotiating on gas contracts won over the franchises from BP to Phillips.
As much as I like BP, lets say hurray for the home team! Phillips is an American owned company and largest independent petroleum company in the world, your dollars stay in the USA as they are based in Houston Texas... I can only suspect they are making a BIG play on acquiring fuel contacts with major franchise holders in the USA.
