Thrifty - Thrifty's Cancellation Rules?

I have two cars booked for LAS coming up and I am not positive which one I will keep. I would like to keep both reservations for now and cancel the one I will not use once I get to LAS. Does anyone know what Thrifty's policy is for cancelling a reservation?

Unless you have some very rare special weird discount thing or have reserved one of the special collection luxury cars (Mercedes, etc.--not the regular luxury Chrysler 300s), no penalties for canceling or no-showing.

Terms and Conditions in your reservation should specify if there are any penalties.
