I've got Avtrip, Flybys and Pilotplus-something in my wallet. I can't remember where I got any of them. Most FBOs use Avtrip. I think Sheltair uses Flyby.
I've got about half a dozen savings bonds around here thanks to Avtrip. Now I just need to survive to age 60 when they're mature, so I can cash them out for the ability to buy a cup of coffee.
