I have been using AutoSlash for quite awhile and I highly recommend them to find good deals with rental cars. Actually, I have recommended them to family and friends. They are prompt and always try to help with any issue that come up and they really do get the best deals. Plus, once you book a deal they actually "track" your reservation and you can rebook if they find a better deal and cancel the previous deal with no penalty, plus you do not have to prepay! I have dealt a few times with Michael and he has been a life saver and has gone out of his way to resolve an issue that I had recently. I just learned that they now have HotelSlash and I already signed up to start looking up hotel deals!
