Yeah ordering from Europe is the best for these kinds of things... when I got my Sparco bucket seat I got it for ~$500 CAD or so out of a store in Italy. To my door including shippings + taxes it ended up being right around $700 CAD. And I could easily sell it on kijiji or fb marketplace for $850 or $900.
Still doing more research and found a couple more places, one of which is LLL Parts out of the UK. 400 Euros is a pretty good price, especially if shipping isn't too much!
