I am complaining about the changes that have been made to the UDrive as far as earning discount amounts towards fuel. Now they expire in a month and this gives me a reason not to stop at UDF any more to use this perk. I loved that the points did not expire and so I could accumulate for a few months. Now I am no longer interested in going to UDF as often to earn the discount. This was the major reason why I frequented UDF so much. Now you are no better than any of the other vendors that offer discount fuel points. I will not be as anxious to go to UDF now as the benefit has been taken away.
