FWIW, my personal experience has been about 90% success rate. They have a pretty specific case that they don't support, and it's almost always with old systems. My use case was rewards program based, e.g. a gas card.

Obviously, YMMV and I'm in a major city, so it might not be as useful in the sticks.
