Autoslash has consistently saved me money. Whenever I have a rental, I check it a week before I am about to travel to see if the price has changed. Twice this year I have rented with Autoslash, and the price has saved me at least $30 each trip! At least 9 out of 10 times they will be the cheapest, and it is nice to not have to do all the work to save a few dollars!
