I am a long time Amiami user who just recently placed my first post-tariff order with them now that they're shipping to the US again.
I placed an in-stock order on Dec 31, took exactly a week for the invoice to come through (usually was about 2 days), which I immediately paid on Jan 5, and now I'm still waiting to hear about the stuff actually shipping. From what I've gathered on Reddit, this is the new norm. They're so backlogged and the shipping services will only accept so much every day.
Shipping was $40 for ECMS with no fees upon delivery. Up from like $25 for DHL which took about 1 day for delivery from Japan to Ohio. Still a little cheaper than BBTS and BBTS still hasn't gotten the Figma Snake I ordered in stock yet.
Might send them an email. See if it's shipped and they just haven't sent a notification yet like SalemCrow had happen.
