Budget Car Rental Budget Extra daily fee for toll-collecting device, even if only used once. Internet

We rented our Budget car in the Orlando area and everything was great, except we didn't realize, until after we got home, how much of an extra fee is added on for the toll-collecting device mounted in our car.  To Budget's credit, it was in the fine print of the contract, but I wish attention would have been called to the fact that even if our car goes through one toll plaza on one day of our rental, we would be charged a daily fee for the entire rental period, for having this convenience (plus the price of the tolls).  We had about $15 tacked on to our rental price but couldn't have avoided it.
