small run tuck boxes?

I know nothing about this place, except that they posted on a computer game development forum I visit, and they make all sorts of box types involving various kinds of tucking, and their site says "Low minimum volumes: 1,250, 2,500, 5,000, 10,000, 20,000":

They consider themselves a co-op, somehow involving consolidating multiple orders to make it cheaper... not sure I get how that works, but it's what they say!
