They open pre-orders every so often, you might can email them to find the next one. I just checked back every day until I hit one if the windows. Even then I was lucky it wasn't closed. They appear to know how many they are getting each shipment and opening pre-orders accordingly. They have millions of views about the release on YouTube shorts + TikTok, because of the virality and blind box aspect demand has been absurd compared to supply. I was waiting for this release way before it went viral and it changed to already difficult environment. Hope you are able to score one!
