Erev Pesach Matzah:
The custom of all Jews used to be to knead and bake the Matzahs for the seder on Erev Pesach after midday. Due to the nature of the baking today, which does not take place at home, but in the local Matzah bakery, this is no longer practical. Nevertheless, bakeries do have limited groups of people who bake on Erev Pesach after midday, and usually these Matzos sell for a very expensive price, and are known as Erev Pesach Matzahs.
 Admur 458:2
