Hello all, I’m brand new to the forum so forgive me if information about this is already posted somewhere on here.
Currently I’m buying Japanese boxes from Amiami but I’m wondering if there a cheaper place to buy them and in large quantities and have them shipped to the US?
I just use Ebay.
What is the shipping cost with Amiami?
Before covid it was Amiami. Now it’s just me me. 
But seriously it’s just eBay at this point. I have one of the free remaining overseas distribution lines and typically sell out of the newest sets within a month. Japanese rebel clash lasted about 2 weeks before I sold out.
Have you already ordered Infinity Zone from Japan? Really looking forward to the english release for darkness ablaze.
Yes I paid my invoice and just waiting for shipment.
I’ve also bought straight from amazon at amazon.co.jp
Personally, I always use a middleman and buy directly from the pokemon center:

Turns out cheaper for me, but I am in the UK, so your current method may be cheaper as I don’t know what the shipping costs are from Japan to the US.
I have tried a few places and have always found I just end up regretting not just using eBay. eBay has been the cheapest and easiest for the majority of my sealed Japanese product new or old.
thanks everyone for the input.
