Why is it so hard to find kosher for passover matza?

I was trying to find kosher for passover matzah last year in Denver and all of the grocery stores were out, this year I was mountain biking in Santa Cruz the Sunday before Pesach so I decided I would visit the Safeway there – I figured since most of the Jews in Santa Cruz are in the closet (UC Santa Cruz is notoriously anti-Semitic) they would have a load of matzah, but to my surprise all they had were 5 or 6 different varieties of matzah that said in fine print on the top right corner of the box that it should not be used on Passover.


I made the following video before realizing that there was a large pile of kosher for passover matzos in the front of the store, but I found the video funny anyway so I here it is.
