I priced my car rental at 579.00 (Thrifty) after shopping and shopping. Pick up in L. A., dropping off in Phoenix 8 days later. I stumbled upon Auto Slash and inputted my information and every few days I would get an email saying they found a cheaper rate. The Autoslash rates when all the way down to 174.00 (Hertz) and I pulled the trigger. I prepaid, and called Hertz to confirm everything was legit. It was. I just got home from vacation and very happy I saved 400.00. I am really still shocked. Thanks Auto Slash!
