Autoslash.com automatically tracks and rebooks your car rental

There is a relatively new website called Autoslash which will check your existing rental and rebook it if the rates fall, automatically. This saves you from checking and rechecking manually to see if the rate has dropped.

It also has a search facility for searching for rental companies with the lowest rates, and automatically adds the best public coupon codes to give you the best rate.

How it works.

I noticed they dont list Alamo.

For the booking of initial reservations/comparisons you are correct, but for the tracking an existing reservation for price decreases, Alamo is included.

I'm interested in hearing about firsthand experiences with this site. I have a car booked with Alamo for 3-25 at a good rate using coupon codes I found here, but I don't mind saving more if this really works...
