Drivers traverse Web to find cheap gas

They say time is money, but when it comes to soaring gas prices, a few extra minutes online can also save you cents--up to 40 or 50 cents per gallon.

That's what resourceful consumers have been learning in recent weeks as they visit--by the hundreds of thousands--gas price Web sites such as, and AAA's Fuel Price Finder tool, which can be found through the association's Gas Watcher's Guide.

According to that site, one San Francisco gas station recently sold regular gas for $3.20 per gallon, while another--just three minutes and eight tenths of a mile away--sold it for $2.80 per gallon. That's a 40-cent per gallon difference, or a $6 difference when filling a 15-gallon tank.

Those users were likely finding their way to the Fuel Price Finder tool, which uses data from recent credit card transactions to calculate how much people have paid for gas.

It recently conducted a survey that found the prices appear to be changing driving habits: The survey showed a 6 percent drop from last summer in the number of people driving 500 miles or more on a summer vacation, Toews said. founder Brad Proctor said his site got about 1 million individual visitors in all of July, and then 1 million more in just the first five days of August. So far this month the site has had about 4.5 million visitors, or about 236,000 a day, he added.

Proctor, who appeared as a guest on "Good Morning America" on Monday, said his site rewards gas stations with the best prices and punishes those with the worst prices. More importantly, he added, it "shows the economic power" of the everyday consumer. He envisions a day in the near future when people routinely access his site from their cell phones before they purchase gas, he said.
