It never says free shipping, just shipping included with the cost.
You could buy round-trip tickets from JFK to Narita for a family of four for those damn seats- in business class.
I sure hope shipping is covered!!
So why does the total charge change when you select a different ‘ship to’ country?
Duties / taxes maybe? Nismo has an office in the US and I’m sure is registered as a company here so it’s conceivable they are able to bring it in as inventory and process the sale in the US so you don’t get hit as hard with that stuff. Whereas in another country the order may be processed in say, Japan, and you have to pay duties as if you are bringing in goods from overseas.
