Tesco has restored its lowest priced matzah to 29p a box after briefly raising the price to 59p. It has pledged to keep the Israeli matzah at 29p until the end of Pesach.
A spokesman explained: "We work hard to keep prices down for customers across the store and prices do change from time to time."
Kosher store bosses have accused Tesco of taking their custom through loss-leading offers.
