We use Australia Post for all our products, which ensures that you will receive your order in a relatively short time frame. All postage costs include postage and handling charges.

All orders are processed promptly, and if in stock are dispatched as soon as payment has been confirmed. We will notify you if an item is not in stock at the time of your order. If you would like any further information on any of our products, then please contact us with your enquiry.

Please note: we cannot foresee every possible packing combination owing to the many different items and sizes we stock, and the shop may over-calculate postage as a result. For example, what the shop thinks needs two or three boxes may well fit into two or even one larger box.

If you are getting postage shock during checkout, please do get in touch to confirm if a better price is possible.
