Unleavened bread is cheaper immediately after Pesach. It loses its mystic powers and becomes like a simple communion wafer, which needs extra magic to transubstantiate. Without the specific prayers enabling this, you may accidentally be eating the body of Naphthali or other lesser Biblical characters. Make sure you carefully read the "Nutrition Facts," that will give you a clue as to the efficacy and digestibility of the wafer. Pay close attention to the sodium content.
