There's an auto-queue and at the time of writing this there's like 3600 people in it (and an estimated like hour wait), so no guarantee of anything being in stock by the time you read this; but I figured I'd post this in case anyone was waiting on them to restock. 
They ran out of Kaubars right when I went to check out, was the last of the Kufiyas, gonna have to wait cause they sold out of everything quick which itself is awesome that there is this much demand for them
