Get the App, Get Gas
SmartMoney reports on the 10 Things Gas Stations Won't Tell You:
"You can't actually buy gas online, but Web resources can help you find the cheapest fill-up in town. Among them, GasPriceWatch.com and GasWatch.info help people track pump prices.But the most comprehensive of the bunch is GasBuddy.com, which includes a network of 174 local sites, complete with maps and message boards that tally gas price by ZIP code. People are frustrated by the variation in the price of gas, says GasBuddy.com cofounder Jason Toews, and they are using the Internet to take control."
"It has worked wonders for Sue Foust. Every day, as she passes roughly 10 stations on her commute across Tucson, Ariz., Foust makes a mental note of their prices, then posts them on TucsonGasPrices.com, a local affiliate of GasBuddy.com.
Then every four days or so, when she needs to fill up, she checks the prices others have posted in her area. It turned out the Shell station she used to frequent is one of the most expensive in the city. Now she fills up elsewhere. I really do feel like I'm saving money, she says."
The GoodI have used both the Android and iOS versions of GasBuddy - both are free. The feature set is sparse - basic sorting by price, Octane, and proximity. At $3 a gallon I might not pay much attention, but at $4 a gallon, I'm going to take 2 minutes to save some money.
The Bottom LineIn Round Rock, Texas the price variation might be as high as 25 cents per gallon, or about $3.50 per 14 gallon tank... enough to buy a gallon of milk, or to feel less guilty at Starbucks.
