shows you where to get cheap gas, a web site devoted to helping people shrink their bills, a noble goal, has another new service: helping people find a station with the least expensive gas.

If you're someone who drives long and far, especially if you have a daunting commute and are behind the wheel a lot, I can see how it could be a godsend. Admittedly, since I work out of my home, I don't spend too much on gas, though my wife more than makes up for that.

So I tried it out. Go to and click on the button that says "Gas Prices," to get started. It asks you for a home address and a work address, and so if you don't have one, I'd suggest putting in an address to a relative, or the YMCA or some other place that maybe you visit regularly, and after a few moments, you'll get a map and a selection of gas stations. I put in my parents' house and received four gas stations between here and there (but could have gotten more, if I had rigged the settings differently). Seems my cheapest option is $1.88, midway on my journey.

Elsewhere on my route, it's as high as $1.94.
Of course, you can find out this sort of information at other web sites that specialize in cheap gas, but here's where Billshrink goes beyond that. The site asks for the year, make and model of your car, and thus, it can tell you how much it'll set you back in gas if you have to detour off your route to one of those stations, and to the penny, it can tell you how much it costs to fill up your tank at these gas stations. No more guessing.

And the difference in filling up between my two stations -- $1.88 at one, and $1.94 at another? Well, I'm filling up for $31.95 at the cheaper station, and it would cost me $32.99 at the most expensive one. So I'd spend an extra $1.04 at the more expensive station. Did I really need to know that? Probably not -- obviously, the cheaper station is the better bargain. But for the "gee whiz" factor, as well as offering some important information, there's a lot to like in this new feature.
