Do you have internet connections? If so, you can search Dart's Advantage Fuel Network for the best deals on fuel.
It's easy! Just log on to "E-Driver" on Dart's web site and enter your driver number and password. Once you are logged in, click on the "Fuel Discounts" tab. Now select a location (city and state) where you want to search for fuel prices, and a radius (in miles from that location).
Hit the "Get Fuel Stops" button and the results will be listed in order from the least expensive fuel stop at the top, to the most expensive. All you have to do then is decide where to buy fuel and start collecting your Advantage Bonus Bucks!
