I would say dipped, not tanked. It did look shaky at first, but things have mostly returned to normal, at least in Sebastopol. I still see lots of local goods, especially produce, and a lot of the same friendly staff. I find their customer service friendly and effective.
I agree about TJ's prepacked produce. Doesn't work for me.
I appreciate that people support local Andy's, Fircrest, Bill's, and Community Market. For health reasons, I really have to get everything in one place. For affordable, mostly all organic, that's Whole Foods.
