I have checked several so cal places and they have always been oos.
I even asked the clerk about them and they said they just brought out a bunch a couple days ago.
Maybe someone bought them all.
This was about two months ago and they still have not replenish their supply.
However, places around me take 2-3 months to replenish supply so I do not think they are gone, just taking a long time to receive some more.
