That's interesting, but not that much use for me. I've found that in my neck of the woods, the relationships among gas prices at different gas stations is pretty much constant. In other words, if station A is $0.02 higher than station B, and station B is $0.05 higher than station C, those differences remain constant as prices fluctuate up and down (and up and up). So I don't really worry about shopping around--I know which of the stations along my usual haunts have the lowest prices, and make a point of stopping at them.
