Postage rates are difficult to calculate so I've got a guide below to help you. I can post 6 melts for 4.35. I can post up to 20 melts for 5.60. Anything over 20 melts I just charge a flat rate now of 10.00 and that includes everything even if you add candles, jar candles etc. 10.00 is the most you'll pay to anywhere in australia for any amount of items. Hope this helps! Please Note I cannot be held responsible for items stolen in the post! Recently I sent out 2 parcels to the same person and this person claims they didnt recieve either! I find that hard to believe when I sent out 2 identical packages. Australia post is a very reliable service and after sending many parcels over the years I've only had a couple go missing but I suspect fowl play on the part of the recipient. Or, get a larger mailbox with a lock if you are a regular ebayer. I have a big one with a lock and never have to worry about mail being stolen!
