What I don't understand is around here, the same chain's price will vary by several cents, depending on what corner it sits on. In this particular case, I'm talking about WAWA, one of the cheaper chains in my area.

The neighborhood EXXON is now offering 20 cents off per gallon if you also purchase a car wash at the same time. Price of the carwash is $11.

I'm still not ready to part with my gas guzzler...just not yet.
