Shipping & Delivery

Our delivery policy is simple and straight-forward:

All deliveries are done using door-to-door couriers and your order is fully insured from the moment it leaves us, right up until it’s in your hands!

Currently, all orders placed online can only be delivered within the borders of South Africa. All orders placed on weekends will be processed on the Monday.

All orders received by 11 am will be processed the same day and dispatched the following working day on condition that payment reflects in the bank account of Monthly Madness and assuming no stock availability issues.

We charge a flat delivery fee of R79 per order anywhere in South Africa. Other retailers might advertise free delivery but they simply load the delivery fee on each product they sell, which results in you, the customer paying much more for delivery than what you will with us.
