They probably ordered it from 2nd in Japan. As far as I know BiG doesn't have Sams with arcs.
Things have changed, Levi's doesn't seem to be that interested in going after the arcs any more, plus I think Samurai changed their arcs enough to stay out of trouble here in the US. Starting this year, Samurai is even going back to the regular yellow arcs on at least some of their models. As far as I know, no Samurai retailers anywhere remove the arcs and tab any more.
