Safeway in the Bay Area regularly comes up very close to the same cost as Whole Foods, unless one regularly uses the app and clips the saving coupons for Safeway.
Ranch 99 and the little De Martini's produce shop undercut Safeway prices on produce in Mountain View. The comparable items work out to be less expensive at Trader Joe's versus Safeway, too, last time I looked. Produce at Costco is regularly less than all of the above but I only buy a few produce items that I can freeze for later use there. For me the two advantages to Safeway are the extended hours of operation and the locations being convenient.
