Just a word on Fox. You might be able to save a bit but after they bring you to the car rental location you will wait for another shuttle to be taken to the Fox location. Not knocking them as I know someone who is very happy with them. I was all in at Super Bowl week with Alamo for a mid size at $127.69.
I booked via Costco. $6X.XX for the car and $6X.XX for the taxes and charges.
Car was a Dodge Avenger 1200 miles on it. I looked at about 10 cards before finding this one what was "SU" condition.

A Hamilton coupon lot upgrade would have bagged me a full size like a Chevy Impala but I was alone and didn't need the space. The Avenger was great on gas and also had plenty of pep and handled well. I normally go with Dollar but this time around 1 week before I left I found this great Alamo rate. Alamo now the last 2 times for me.
