Cheapest not always so.

The initial fee you pay upon booking is a booking fee which is not deducted from the actual rental in my case R833.11. They are a third party that pass your booking on to the actual car rental business. Mine went through First Car Rental. I feel this bit of information should be clearly stipulated. They obviously get cheaper rates but with this booking fee your rental will probably work out the same if you went directly with the rental company.
