Like hotel and flight prices, rental car prices can vary based on a variety of factors. As a result, the price you get when you reserve a vehicle won’t necessarily stay the same. Depending on the different factors impacting it, the price can go up or down. One of the benefits of AutoSlash is that it will track the price of your specific reservation for you, and if it goes down, it’ll let you know so you can cancel and rebook to save money. Of course, some car rental companies offer the chance to get a discount when you pay now instead of when you pick up the car. In these cases, there’s typically a fee associated with canceling the reservation. If the new price through AutoSlash provides savings that are greater than the cost of cancellation, it’s still worth it. But if not, you’re better off sticking with your current reservation.
