FWIW, those observing kosher dietary restrictions will have some difficulty with this otherwise great deal.
The Lays are O-U, at least every time I have seen them.
But the Fritos and the Sun Chips are Triangle K; my LOR does not approve of this hechsher.
The others -- Doritos -- lack a hechsher in the US. (Oh, but in Israel, I think they are Bedatz...so awesome!).
