I guess it depends on what proxy you used. When using DeJapan you need to ask for the shipment once it has arrived and then you get the invoice for the shipping cost. Hopefully you will get it soon!
I would say it would be between the VF1A Max and the current prices for VF1S Hikaru, between 22k and 26k yens but after some weeks, not days. Max is also getting scarce every day on YJA also, let's see what happen in the next few days and wait for a good deal.
I was able to get a new Sentinel Legioss yesterday from AmiAmi but today orders are closed, it seems I was lucky! Perhaps is worth to keep checking again if someone is still interested on this figure https://www.amiami.com/eng/detail/?gcode=FIGURE-054517
You can activate alerts for specific items at Mandarake, they usually work OK, you will receive an email when an item of your interest is posted which is usually which in early AM hours central time.
Yes, like someone else have already mentioned it would be about 4,500 yens by EMS, I have already ordered one of this from Mandarake and they charged me 4,550 yens.
I got the 28k shipped to Mexico by EMS for 5,200 yen. I activated the alerts for this one some days ago and as soon as I received the alert on my email I ordered it.
This one is on Yahoo Auctions right now but most likely it will reach the 36k yen: https://page.auctions.yahoo.co.jp/jp/auction/q387012144
