All tubes are guaranteed not DOA. Shipping is by Australia Post and charged according to their rates for different zones around the globe. If you wish to check out the zoning and charges please visit auspost.com.au. The minimum shipping weight is 500gm, I pack tubes very well and I have only ever had one problem with damaged tubes in over 10,000 sales. There is a very small handling charge to cover packaging and handling. I do not profit from shipping and I wish I could charge less. I am a registered business and pay all the appropriate Australian taxes including 10% GST. Domestic shipping for this item is $12. Overseas shipping costs depend on the Australia Post destination zone.The charge stated in the invoice will be for Europe where shipping with tracking is $28. Shipping to the USA with tracking will be cheaper at US$22 as it in a different zone from Europe. 

If you live in a cheaper zone than Europe I will refund the difference ASAP on payment. Please Email me to know the specific shipping cost to your country.

Please Email me if you have any questions about this item and I will reply as soon as possible
