@winstonparkerley: Filling up hits a little different when you know part of it is coming back to you. As a @Flexcar member, I'm automatically enrolled in their Gas Saver program, so I just pull into a participating station (the Flexcar app shows me which ones are nearby), fill up like normal, and save up to $0.60 a gallon, which adds up fast with all my back and forth between New York and Newport.
