If you don't mind suffering thru a ERAC car, Enterprise is offering a $10/day Off coupon that can bring some rentals to $5/day or less after taxes. This is a great way to get an Extra Emerald Club Rental Credit towards more free days.

To do this go to: www.enterprise.com and log into your National Emerald Club account (it's under the "Loyalty Programs" link).

Once you are logged on, click http://www.enterprise.com/car_rental...110P03_ES10DOB and book your reservation. Before you book, ensure that you are still logged into your Emerald Club account (this way you'll get credit). Then pick up your car and enjoy the cheap rental credits.
