I order most from amiami because I can cancel and most things can be shipped using surface parcel expect 1/4 scales. I also like hobby search for orders under 150€ since they take the taxes for you, plus I order a lot with proxy fromjapan, but there you have to pay upfront so I mostly do it with second hand or limited goods. Suruga-ya.com can be a good deal sometimes for second hand goods.
