So I made a reservation without logging in in order to get the lower rate.
Then I called AVIS and had them add my Wizard # to the reservation, thinking that I'd be able to snag that lower rate. It ended up increasing the rental price significantly, more than what I would've paid had I just logged into my account to book the reservation.
Did they close that loophole? Doesn't make sense for me to get a lower rate when not logged in.
