I just used this...you need a Visa card. But I got my car rental down to $140 for the week from the $200 reservation I had before. Save up to 20% and receive $30 off when you rent any size car in the United States, Latin America and Caribbean and pay with your Visa® card. Requires a 5-day minimum rental with a Saturday overnight keep. To redeem this offer, click the link below to book online or call Alamo at 1-800-462-5266 and request ID 7015504 and Coupon Code AD2338FDF. I did it online and just used cut/paste to fill in the boxes.
