FAR MORE DOWNSIDE THAN UPSIDE: You get good "deals" on this app for a day! After your initial use, it's kind of a joke. And the apparently "good deals" turn out to be insufficient stations that either have their outside payment machines down, requiring you to go inside to pay cash, or the pumps are out of service. Today, I drove my diesel Power Stroke into town and their map is full of 1 cent savings! Wow!!! What deals!? When the prices go up, the discounts go down. More trouble than it's worth.
