Hi,
it was the same for me here in Europe.
I purchased one model on ebay on 12.5. but after many weeks of reading the news of Japan Post (
https://www.post.japanpost.jp/int/in.../index_en.html) daily I decided for shipping by DHL which was the only operating courier service to Europe.
This cost me USD 3 more and because of customs clearance by DHL I had to pay also the double collecting/handling fee (USD 20) than Austrian post will charge me plus 20% import tax of course of total amount (model price + shipping).
Since 19.6. Austria is deleted from the suspension list but still to 140 countries/territories Japan Post will not ship and therefore acceptance of such mails will be rejected.
So please check if DHL or any service is currently shipping to the US if you will not wait some more weeks for your model.
Regards,
Wolfgang
