You think that’s expensive? Try getting shmurah matzah out of town (and I don’t mean Lakewood or Monsey). Down here in Atlanta, it’s upwards of $30-$35 a pound, imported from Brooklyn (I don’t hold by the mass-produced stuff in Costco). And you only get the one brand/hechsher the supermarket chooses to buy that year. There’s no wall of shmurah matzah from 10 different bakeries with your choice of white, wheat, spelt, oats, etc. I drive to Brooklyn every year before Pesach to load up my SUV with Pesach food that you either can’t get down here, or costs 3 times the price.
You should be thanking Hashem that you live in a place where the necessities of Pesach are so readily available and at relatively reasonable prices.
