Subject: Re: LBYM travel
AutoSlash is a nice little travel hack for rental cars, at least domestically (haven't tried it for international travel).

The way it works is you enter your reservation details, and they'll email you when they find a lower price. Rental cars are easy to rebook as long as you don't pay up front. I have an upcoming rental that started out at $165 and I've rebooked it several times, now down to $115.

It's not going to be as lucrative as CC churning, but kind of enjoyable.
