GasBuddy.com
GasBuddy.com was developed as an initiative to provide the general
public with access to local current gas prices. This is an entirely free
service that depends on users to input gas prices on a daily basis to
keep the database of prices up to date. Since the price of gas is often
extremely volatile, posted gas prices may vary as much as 20% within
only a few blocks of each other. By having access to the most recent
prices at GasBuddy.com consumers now are able to locate the most
inexpensive fuel price in the city and fill up on a budget.
