There are a bunch of websites and widgets out there offering to help find the least-expensive gas, so I thought I’d throw this link out there, too. It searches prices by zip code and offers up a calculated average price for the zip code, along with the highest and lowest prices/spots, too. Prices seem to be slipping a bit lately, but saving 10 or 15 cents a gallon adds up, particularly since you can pinpoint the stations by zip code. If you have any favorite links you’re using, please pass them along here, too…
