I recently sold a 750 gas tank to a fellow in Australia. The post office website said it would cost $80 to ship. So I pack it up and take it to the post office. Then the clerk tells me that Oz has size restrictions that make it more expensive than other destinations.
He says that it will cost around $150 instead!

Has anyone here had experience with shipping larger items to Australia? What are my other options? I haven't checked UPS, FedEx or DHL yet, but I suspect they won't be a lot lower.
I am afraid the buyer thinks I am trying to jack up his costs for my benefit. I just need to find him a reasonable quote!
