I have used Autoslash for years when renting cars. They provide the service that I HATE to do...checking prices constantly to make sure that I get a good deal. With rental car rates so high now, this is needed more than ever. I made a reservation 2 months ago, and gulped at the price of my rental. Today, I found what I thought was a much better rate myself, and emailed Autoslash to find out why they didn't see it first. Very quickly they told me why I shouldn't go for the reduced rate...it was non-refundable, and could have been a bad choice, if rates continue to decline. And, after saving me from my mistake, they found even BETTER rates for me! They saved me hundreds of dollars on my rental. Their customer service was excellent. I will continue to use them whenever and wherever I rent a car. You should too.
