The SS-15 Studio Series Bumblebee with car parts and Charlie figurine is now listed on Amazon Australia as imported stock, for only AU$37 (currently with free shipping if you are a Prime member)... that compares to $60 at Toyworld/Toymate, and about what it cost me to get one directly from Amazon America a few months ago.
That's more like what it should be worth, only being a Deluxe toy with a few plastic accessories and sticker sheet. Since it is a box that's almost twice the size of a Deluxe SS box, it naturally gets double the price by Hasbro as well.
