I POed Wasp at BBTS, don’t mind waiting for US release, almost the same price as importing but getting a stand for it.
Thor I went with bandaionline.com Around $85 shipped.
I have ordered from them before. My hot toys Hulk shipping was $25 from them to California. They only use USPS or UPS therefore their rates are kinda high.
For the hulkbuster I'm guessing shipping would be around $40 bring the total to $800. Still cheaper that ssc or bbts.
