SWIPE & save STILL not working

I have to wonder if these programs really have much value. On my last long trip (between DC and FL), I stopped at Pilots and Flying J's exclusively, access permitting. I kept my receipts and found that I saved approximately $3. There was no notable price difference on diesel between these locations and others I saw in their general area.

I stop at PFJs simply because I know that it's almost always an easy in and out and I don't have to worry about navigating hazards, other than stupid or oblivious drivers.
