Booked a car in Europe and had a confirmation "pay later". A week after that my Amex gets hit with the full rental charge. Went to my reservation and it now showed "prepaid"!

SCAM

I called to cancel the reservation then proceeded to do another one for the same car, same dates, same Location. Price was half of my previous reservation.

SECOND SCAM

So they lock you down by converting the post pid unto prepaid just before their rates drop by half?!!!
