Star Wars Black Series Darth Vader Centrepiece $36.36 + Delivery (Free with Prime) @ Amazon US via Amazon AU
Just saw this scrolling through Amazon daily deals, was listed for $57.95. On clicking through the price dropped to $36.36. Would usually be about $22 postage, ruining the deal, however it becomes a great deal with the current free US Prime delivery offer available.
There is also a Luke Skywalker figure in the same range available for $47.77 from Amazon US ($54.00 from Amazon AU), however it's temporarily out of stock, but still available to order.
