How are online parking charges calculated?

Online parking charges are calculated at a discount compared to the standard (not pre-booked) charges. If you book >5 days in advance you get a maximum of 50% discount, 4 days in advance 40% and so on. If you book at least 1 day (24 hours) in advance you still get a 10% discount.
Example (Booking 10 days in advance):
Multi-storey Parkade 2 North
Enter car park: 9am Monday
Exit car park: 9am Wednesday
Pre-booked parking charge: R125 (50% * R250 for two days regular parking)
