I've experienced this problem before. I usually call up web services, explain the problem. Depending on the representative, my experience is that they will:
a) make a reservation for you at the higher price
b) make a reservation for you at the higher price and then put a note in to waive the ticketing fee
c) somehow make the reservation for you at the lower price after doing a lot of manual intervention
The reservations they make for you cannot be purchased online -- they will require you to call in to purchase.
