isa,
On top of that the Pri”C is also chumarah as per the Noda beYehuda. See the very SHA”T the N”B stating that even on the Matzos of the first days the minhag was to use non-shmurah
ZD,
As per the Noda Beyhudah and many others if you can not afford it – you can certainly eat it on the rest of the days and no need to say children..
In my opinion, the flour they use could very much be much better than the flour (Kemach Min HaShuk) the N”B and the Pri”C is referring to (if it has a good hechsher)…
