Dirty's Chips in the South Bay
You can try Milk Pail grocery in Mountian View. I have seen it there before. They also carry California chips too (I think it is Dirty Chip's second brand). They sometime have it at the Red Rock Coffee in Mountain View off Castro street. It is in their bin of chips. Good luck.
Mollie Stone's in Palo Alto had a lot of them.
They had a great selection too, and a good price. They were only the 2 oz bags though. I haven't seen the 5.5 oz bags at the stores I normally go to.
