Ha, I feel your pain! The same thing happened to me a few weeks ago with Ezekiel bread. That item was the reason I went shopping, and they were out.
My store put up a sign though, explaining Ezekiel stock would be low/missing because Ezekiel had a fire at their factory. My store has some in stock now though, but noticeably less than they'd usually have on hand.
Hopefully WF will have some.
