Here's one for all you fans of travel hacks and ways to decrease business expenses in general. The FlightCar service rents out cars left by people when they're off traveling the world, to those landing at the airport and needing a car.
That's a great service, but they've gone one better with their FlightCar Monthly service, which offers people a flat fee in return for the use of their car for a month. If you need your car back within that time, you get 4 free days with your car, or one very like it.
This is great if you don't use your car that much, but need it for things like family vacations - or if you don't need it for a month because you're off on a long vacation yourself.
All in all - works well for everyone!
