give it a shot, put in your details, you have nothing to lose, worked very well for me, the trick is to use various CDPs on the Hertz site to determine the best deal, for them to then better, autoslash, as i understand it, relies on the CDP you provide in your initial booking, and then continually hunts for a better price, up until the time you get the car, there's no downside. i spent a good bit of time looking at comparables across sites, other car rental companies, and the consolidator/travel agency type sites, and autoslash generated the best deal.
