Transfercar is an online relocation service providing really cheap (usually free) rental cars and campervan hire. With "free" we really mean the cars are free to drive, not even $1 a day! We don't charge anything for this. How can it be free? Rental car or camper van companies need to move cars between their branches all the time. They can either use expensive trucks or trains or they can let you drive it for free. The rental operators win, you win.
