I would love to find a Bay Area source for the 25Kg bags. Locally the 1Kg bags are $3.39 at Whole Foods and I've been unable to beat that price in any size from any source once shipping is figured in.
At least the stuff from WF has been reliably fresh. Probably become some bonehead keeps showing up and buying up all their stock
I'm going to be in Sacramento on Nov 1 and plan to visit Taylor's Market. Maybe that's a winner, but too far to go just to buy flour.
