For about 10 items (includes one smallish ornament), postage was $86.60 (!!). But it still works out pretty good in the end.
The more you buy, the cheaper it works out overall for postage. When I started out with 5 items, postage was almost $20 per item cos it was already 86.60. I think the min postage might be $86.60. If you register with address and login, the View Cart will display ongoing postage for international. For me, it stuck around 86.60 and if I added more items, it would have been $117.xx, so I culled to the max items for 86.60! Could have bought heaps more for extra $30 postage but that would involve spending more money on the items too so I resisted. Unfortunately I encountered some Avengers stuff that did not allow it to be shipped internationally. It states that in the Delivery section for the item. Also, Disney Store delivery timeframe and customer service has been very good in my past experience.
