I've never shipped outside of the U.S., so I don't really know how this works. Does customs charge a fee? My buyer's from Australia. I want to ship it to her in the cheapest way possible, so she doesn't feel like she's getting ripped off but at the same time I want to make sure everything's insured and tracked. Any advice would be wonderful..TIA!!! P.S. I'm sending a small leather jacket, so I'm guessing the total weight would be somewhere between 1-3lbs.
