IMPORTANT: 1) Standard postage cost for up to 3kg is $15.40 incl GST, and $31.80 incl GST for orders over 3kg. This postage cost is NOT shown in the shopping cart at present (trying to rectify this), but will be added and shown on your PayPal page and invoice. Please contact us directly for bulk discounts and freight rates for multiple unit orders. 2) Prices and default postage rates are to Australia only. Please contact us via email if you would like to order Adzorbstar and are located outside of Australia, as GST needs to be taken off the prices shown here, and postage will need to be worked out for your specific location. Thanks for your understanding.
