Check Whole Foods - haven't been to South Bay branches, but the ones in the East Bay have been swimming in the stuff.
I can't figure out why Jane's charges a buck or two more for everything when Ava's is literally a couple of blocks away with more reasonable prices. Not to mention Whole Foods Los Altos within driving distance. Buying a handful of things at Jane's easily translates to a $10 premium. I bought Sucks at Whole Foods Redwood City. Hopefully I'll have the chance to buy a few more sixers.
